well u are arguing against having sex in hs which i understand but ive had both types of sex. casual sex and w/e u wana call the sex when ur in a good relationship and it isnt just for shallow reasons. im 16 and ive had sex with 4 girls. i dont regret having sex with any of them. the girls that i had casual sex with (2 of the 4) knew it was casual sex and must have been a part of ur "70%". the other 2 girls i was in a long relationship with before sex happened. the problem with that is both of them were first timers. and a lot of the time when a girl gets in a long relationship and then losses her virginity to the guy, she usually becomes even more attached to the guy. i had to break up with both of them at one point and it wasnt pretty. so there are ups and downs to both types of sex. soo really u need to have sex before u complain about it
