i've known my Boy friend for 3 years, but we just recently started having sex. He was my first and i was his second. Things are great and we are both very happy, but i always want sex more than him. He is as understanding as possible but its still a problem and i feel bad/embarissed for wanting him more. He is just about to turn 20 so i worry this might even get worse. He does work alot, stays up late frequently, and is stressed alot so maybe thats contributing? I just don't know what to do i keep getting more and more frustrated.
