Since puberty, I've never been able to fit in anything bigger than an A-cup — a fact I used to hate about my body. Luckily, I've actually grown to appreciate my small breasts over the years. There are quite a few benefits of having tiny breasts: I can go braless whenever I feel like it, I don't have any back pain due to a heavy front-load, I rarely deal with underboob sweat, and I never have trouble finding sports bras that fit me. Aside from the aesthetic pros and cons, there are some facts about small boobs you should probably know if you're a proud owner of teeny breasts, facts that relate to both your sex life and your health. There might even be a few myths floating around in your head that need to be busted.

Because of our society's slight obsession with breasts, we're constantly talking about their size and shape. Big boobs have lately become synonymous with sexy, perhaps because the average size of breasts has actually been getting bigger as time goes on; in just the last 15 years, women's average cup size grew from a 34B to 36C. Experts aren't exactly sure what the culprit is, although they think overall weight gain in the general population, hormones in food, and the rise of hormonal birth control all have something to do with it. Whatever the reason is, our society is more obsessed with big breasts than ever before, which all too often means small boobs either get ignored altogether, or shoved into push-up bras in order to feign cleavage.

No more! It's time to own your small boobs — and you can start by learning the facts below.

1. Small Breasts May Be More Sexually Sensitive Than Large Breasts

Researchers at the University of Vienna claim that having small breasts may equal more pleasure in the bedroom. The larger your boobs are, the more glandular tissue there is than fat tissue, and the latter is what accounts for the breast sensitivity that comes in handy during foreplay. Alan Matarasso, M.D., a plastic surgeon in New York, explained to Men's Health that "the nerve that transmits the sensation of the nipple is more stretched" in small breasts, meaning it's simply easier for small boobs to get stimulated in sexual situations.

In the University of Vienna study, women with big breasts experienced 24 percent less stimulation than those with smaller boobs. That's nearly a quarter less excitement happening between the sheets. Remember that next time you're climbing into bed with your partner or on your own, and be grateful that your itty bitty titties are working so hard for you to get yours.

2. Not Wearing Bras Can Actually Be Really Good For You

For me, the best part of having small breasts is how easy it is to go without wearing a bra. So I felt vindicated when I heard that science has proven that avid bra-wearing may have some negative consequences in the long run. A French study in 2013 that surveyed 330 women over the course of 15 years found that there was nothing "medically, physiologically, and anatomically" to be gained from strapping into a bra every day. In fact, using a bra could damage your breast tissue, cut off circulation, and eventually lead to premature sagging.

This is especially good news for us small-breasted women, since we can afford to go braless. Women who have been blessed with big boobs can't throw away their bras as easily because, without the extra support, they may experience exacerbated back pain and a sore neck. You don't have to worry about those side effects, though, so it's time to seriously consider doing your breast tissue a favor by giving bras a rest, at least every once in a while.

3. Just Because They're Small, Doesn't Mean They Won't Sag

At teenage sleepovers, when the conversation of boobs inevitably came up, my friends used to console me about my flat chest by insisting, "Hey, at least you'll never sag!" Couple things wrong with that statement: First of all, I definitely didn't need sympathy from anyone. My boobs were awesome because they were tiny, not in spite of that fact. Also, it's simply not true that small breasts don't sag.

Nothing is exempt from gravity, no matter the size. Deborah Axelrod, M.D., medical director of clinical breast services and breast programs of New York University Langone Medical Center, told Prevention that it's not so much the size of your boobs that leads to sagging, but rather what's inside of your boobs. She said, "Whether or not your breasts sag depends on the ratio of breast tissue to fat." So before you get big-headed about you and your small boobs never sagging in your natural life, remember that it technically has nothing to do with your cup size. (Though, as we saw above, it may have to do with how often you wear bras.)

No matter what direction your boobs fall in, though, remember that there's nothing wrong with saggy boobs, anyway. Boobs are boobs, regardless of the beauty standards society has thrown at us, and as long as they're happy, healthy little campers, it's all good.

4. Small Boobs Don't Hold Any Less Breast Milk

Here's another myth that needs to busted: Breast size has nothing to do with how much breast milk you can produce. First, it's important to know that the size of your boobs is determined by how much fat tissue you have, not your mammary glands. So although women with big boobs may have a lot more fat tissue in their breasts, that doesn't mean that they will have anymore milk-making tissue in there.

Whether you will have trouble producing breast milk will have nothing to do with your breast size. No matter what cup size you are, you can also expect to see changes in shape, size, and fullness in your boobs during and after pregnancy. Those puppies can get pretty big and swollen, especially when the milk starts to accumulate.

5. Women With Small Breasts Tend To Have Better Posture

D-cup breasts can potentially weigh up to 23 pounds. Having to carry that around all the time puts a lot of extra strain on your back and can even cause headaches and neck tension. Because small breasted women don't have the extra boobage, we tend to stand up straighter and have better posture overall. Thank your lucky stars for this, because there are a lot of nasty consequences of having bad posture, such as increased risk for heart disease, less self-confidence, and more wear and tear on the joints. So stand up tall and own your little boobs.

6. They May Not Be Small Forever

When I think about how many times breasts can change in shape and size during our lifetime, I can't help but think they've got some serious superpowers. Our boobs are subject to change when we're pregnant and breastfeeding, when we gain or lose weight, or when we simply age. It's perfectly normal, so don't be surprised if it happens to you. How much you grow or shrink will depend on your unique genetic makeup and how much fat tissue you happen to have in your breasts. If you experience any significant physical transformations, just be sure to pay attention to the bra size you're wearing. If your body changes, your undergarments will have to change too.

In other words, don't get too attached to your small breasts. It's like the Buddha said: "Attachment leads to suffering." And I'm pretty sure he was talking about boobs.
