i learned to be a sexual being by mutual masturbation. i never had any problems masturbating in front of my b/f(s)..hehe. PROVIDED they were doing it too...
masturbation is a natural and revealing process. i have learned so much by watching by b/f(s) masturbate about what gets them off, how to do it etc. that helps me when it comes to jerking him off too!
i masturbated for my last b/f one time and just had him sit there right in front of me and watch what it was that made me feel good...then i said DO WHAT I JUST DID AND YOU HIT A HOME RUN!
as far as the "body fluids" on your neck, etc. that is an interesting thought. never tried it or thought about it, but i think that you might have something going on with the idea j3nnyuk.
