well, i love sex with my girlfriend, she's wonderful. but masturbation is different, i can't choose sex or masturbation. probably i can live without sex as i masturbate, but i want to have sex, as it feels good. the reason i don't want to have sex often is because if we have sex all the time, it gets boring, i mean, i don't want it to be routine or anything, i want it to be special. i don't want to have sex just because i have sex urge. i want to have sex when i want to feel sexual and feel like making love to my girlfriend, not just to relieve my sex urge. this might not make sense, but this is how i feel about sex. it's very difficult to choose sex or masturbation for me.
