id rather have sex with someone i really actually love rather than just doing it as often as possible just to do it. so i do sorta agree with him that its good to wait for the right time. but just cause thats my opinion doesn't mean its the right opinion, i think its totally fine for teens to have sex. its a natural feeling and the only reason it could possibly be negative is because our culture makes it that way.
i had a couple friends having sex by the time they were in 6th grade and they a perfectly fine now. ive got friends who are 20 and still havent had sex and they are perfectly happy about it.
its made into way too big of a deal, just do whatever the hell you want with it.
