So... I ended up doing something with a guy for first time and afterwards we find out we're third cousins.

So... Um, I've been curious. I've never done anything with either sex. I'm almost 21. Not sure if I'm gay, bi, or whatever. Ended up making a grindr last month. I didn't plan to use it when I got back home from college but this guy messaged me and we exchanged pics and he wanted to do something so we exchanged snapchats. I'm in a pretty rural area.So I end up meeting him around 8pm last night and we snuggled and touched. Messed with genitals. That's about it, no kissing, neither ejaculated. He told me he's done this with guys 3 times before and women twice. Never penetrated or anything.It felt good while doing it, cuddling, holding, touching. Afterwards though... I just thought it would be more... To it? It was like "Ok, I did it... That's it?".Anyways, we were talking afterwards and he asks for my last name and then we find out we're third cousins. Never met before. Maybe I shouldn't have went and messed around with a random guy in a place as small as where I'm at... I've been thinking about this all day today and woke up in the middle of the night and thought about it for 1-2hrs... I did something and then found that out... I'm confused and conflicted. Also, should I be worried about STDs? He said he's never done anything before with penetration and I believe him. I just can't believe I actually did something... Don't even know how to go about getting tested without parents knowing. Feel ashamed. I don't know what I want anymore. It felt so good holding him and snuggling.... I miss the touch.So, that's my weird story of what happened! Don't know what else to really say. Feel like getting it out there somewhat. Going crazy keeping it in.
