text: Talk to your boyfriend.  This is not "abnormal" sex, there are some people who do this on a regular basis so as not to have full intercourse.  It is still "sex", and can be very satisfying, it's just not full intercourse.  But talk to him and discuss how you feel.  After 2 years together, you should be able to talk to him about this kinda thing.  If not, what would happen if you marry the guy, and you can't even talk about sex!?  Maybe he doesn't enjoy Vaginal sex, and this you need to find out!
