I've been with my 20 year old boyfriend for 2 and a half years (I'm 19). I have no interest in or curiosity for any kind of sexual activity with him yet. He's always been extremely attracted to my appearance and body.

To make things more exciting when we're together, I love to tease him by slowly stripping down to my underwear, then sitting on his lap and kissing him. It's such a rush for me and makes me feel a little dangerous.

He's always been a very sexually curious guy and he's really keen to take things further with me, especially because he's a virgin. He respects that I'm not yet interested in or curious about sexual activity with him and never crosses the line or makes any advances. We've yet to see each others bodies beyond underwear because of my wishes.

Should I stop doing this? He loves me being in my underwear, but I have a feeling that it's driving him insane, whether he'll admit it or not. He's the kind of guy who never loses his cool.
