Sucking/ kissing/ nibbling nipples!!!

So the other day my boyfriend and I were making out and he started fingering me. While he was doing so, he pulled up my shirt and took off my bra and started sucking/ kissing/ nibbling my nipples and boobs. I'm not going to lie, I loved it, and it turned me on so much. I was wondering if anyone else's S.O. does this? Does it turn you on?
