So I’ve been dating my boyfriend for a little over 6 months now and in the beginning of our relationship everything was normal we had sex anytime we had a spare second, things moved pretty fast he moved into my house a month after we started dating. Well i don’t know what happened but we haven’t had sex in over 3 months September 4th to be exact was the last time we had sex, He says he is sexually attracted to me and that he wants to marry me some day but i feel like something is off I need some advice
