I am 21 yrs old an been with my boyfriend for 4 yrs. The last 2 years I've had a low sex drive, don't get me wrong I love my boyfriend and I love when I'm having sex with him, but I just can't get in "the mood" he wants to have sex all the time, everyday and he complains how I never make any moves on him, thats just because I really don't feel like having sex I just dont even think about it or get in the mood anymore, is this normal for my age? an is there anything I can do to make it better?
