No sex drive/ scared to initiate

Sa

When my boyfriend and I first met and started dating (about 6 months ago) we had sex all the time. I was usually super drunk and all over him and it was great. But then we started having sex like once or twice a week, and now we haven’t had sex since Christmas Day. He called me out and got mad bc he is done trying to initiate it all the time, but I’m terrified now and have no idea how, I just feel so uncomfortable trying to be sexy.
