I'm self conscious about my boobs :(?

I'm 16 and my nipples are similar. I was really nervous about my boyfriend seeing me naked and i kept a top on whenever we had sex until i was confident enough to be fully naked in front of him. I now think that I shouldn't have been having sex with him if i didn't trust him enough to even see my body. Guys really like women to be confident with their bodies, it makes them more attractive. So if you feel comfortable I'm sure he'll feel more comfortable. If you really want them to look a bit smaller, you could make them cold (which makes them contract a bit and the nipple pokes out more, making it look less puffy) or lightly rub them, which will do pretty much the same thing. There are many guys out there who find large puffy nipples a big turn on! I've heard it from quite a few guys. Only let him see you if you really trust him and if he makes you feel happy. Never give in to a guy pressurising you. If he really likes you, he wont mind waiting until you're happy to show him.
