You gotta let teens be teens. If her parents ask you about it, id just say, you don't know, and that it's not something you think about.

I lost my dad when I was 11 so when it came to my first gf i was sexual with my mum gave some money for condoms every now and then. But walked in on us post sex when the condom wrapper was on the bed side table.

So told me later she saw it and was happy I was being safe, and if I ever needed money to buy more shed give it to me as well "better safe than sorry"

I lost my virginity at 14 to a 17 year old and I stupidly came inside her everytime. Im lucky she never got pregnant but it's never worth the risk. Especially at such a young age
