My boyfriend and I are 22 and 21, respectively, and have been dating for two years. We recently moved into an apartment and now live together. We're committed to not having sex before marriage, but we've been doing other sexual things since we started dating.
When we first got together, he was somewhat interested in oral sex (me to him, but NOT him to me) and touching and stuff. That lasted for only a few months, and since about a year and a half ago he has lost all interest in it. We'll do stuff maybe once every other month, if I'm lucky. It keeps getting worse. He's never been a very sexual person, and never even kissed anyone before me. He doesn't even enjoy kissing because he says it's wet and messy (even though we only ever kiss closed-mouth).
The only thing he has ever been interested in is feet tickling, which I grew used to. But anymore, he doesn't even seem to get turned on by that. He claims to be turned off by not only kissing, but also breasts, porn, and even the mere thought of a vagina.
