Public stuff??

So I'm gonna be a senior in HS and my bf is gonna be a junior but the last month or so before summer started we've started talking about sex. We sent sexts and it gets me really horny. Eventually we started doing sex-related things.. Except in public!!! At lunch, my boyfriend would rub me and one day he actually fingered me. It felt so good. I was scared our friends would notice but I started giving him handjobs in his pants during lunch too (WE DONT EAT LUNCH BTW LOL). We were alone one night at the park. It was dark and I was literally giving him a handjob with his dick out. I was so horny I almost had sex with him but I was on my period, we had no protection and people were walking around so we tried to keep it LK. Sorry for the details but I needed to share that with someone
