so im 17, ill be 18 next month. ive been with my boyfriend for 15 months and we had sex many times, i started birth control almost a month ago, blah blah blah. he gets upset bc im not all that sexual, understandable. like i dont initiate anything and im never in the mood for him to go down on me(yes-he is good at it) and i kinda feel bad. i want to be more sexually active for him and for myself. any tips on how to increase my sex drive??
