Okay if you REALLY want to do that-

0. Not at all safe unless you do not intend to use hormones- for a purely cosmetic transformation try searching for corsetry stores, any MFT or drag queen, even pinup style clothing stores. Heck, if you're in australia visit Bras N Things and you can be fitted for a bra so you can be naturally given cleavage.

1. If you insist on hormones, which it seems like you want purely for breasts, then definitely go to a doctor. You will need to see a specialist, if you're in the Sydney area see Dr Tracey O'Keefe. She will be able to analyse your situation (with personal experience) and help you professionally.

2. Roughly 6 months to see changes but you will need to continue with a low dose because otherwise you can get very sick.

3. There's a very good chance it will shrink, depending on the strength you may lose the ability to have an erection. A very lose dosage for Estrogen (or testosterone blocker) is a synthetic version of what happens to a fat man- pretty much, when men are overweight they produce more estrogen which most of the times leaves the inability to have an erection, sometimes breast tissue can actually grow, and in really weird cases it can cause excess hair growth.

4. You can still use the same ID as long as you don't apply for a sex change and you don't change your name.

5. You deeeefinitely can gain weight. A higher level of estrogen will increase your chances of weight gain. An overweight man will have greater levels of estrogen than a healthy man. Expect it on your thighs, hips and butt- right in the dangerous parts!! However, if you don't qualify as overweight with the excess weight then it can just look like natural feminine hips :) Expect PMS (without a period, obviously), bloating, tender muscles, a sore throat possibly leading to a very quiet voice, loss of muscle definition and mass (as in lean muscle replacing bulky muscle), pretty much anything inconvenient.

6. definitely don't make a big deal about being trans, try not to mention it unless you're likely to engage in sexual or medical activity with another person. It'll just make passing for either gender SO much easier. Figure out which voice you want, high or low, and start practising HARD.

7. Implants are usually safe. Depending on your weight fluctuation and how you take care of your skin you may need them replaced a few times but most people start small and work their way up large. If they were happy with the initial size they wouldn't need to replace them.

8. Money will vary from $3K to 300K depending on what surgery you get, where you get it done, which doctors you visit, what hormones you take, if you get ID changed, what femininity-enhancing apparel you buy etc.

If you're tight on money, try breast enhancement creams (sooo many brands online), pushup bras and a change of diet- if you're okay with Moobs rather than boobs, try drinking alot of Soy milk. Soy proteins increase "breast" tissue in males and in some cases can give fat tissue on areas that conveniently look like hips.

edit: I'd just like to point out that the person with the most thumbs up to their answer has NOT answered the questions, hasn't offered any advise and has said "i don't know" several times. ..Why is it that the rules for the thumbs up/down system doesn't appear to apply in the GLBT section?
