would friends with benefits work at 15?
as long as your parents dont catch you and you are safe
You absolutely HAVE to be safe dude! Honestly, at your age - if you choose to have sex - that is pretty much all it ever is. There are few long term, committed relationships when you're 14/15. The person you are with isn't going to be your lifetime partner.
But...especially at your age...choosing to have sex with multiple partners is a little risky.
PS - I thought you stated you were 13/14 in previous posts??
