Okay, so me and my boyfriend were fooling around today and I didn't have any underwear on and he had just his boxers on, and he was dry-humping me (thats its). After a while, he ended up cuming. He got off me then. I asked him if he got any on my vagina and he said he didn't think so.
What are the chances of me getting pregnant? It's not like he was getting inside me, he was only ontop of me... outside my vagina with boxers on. PLEASE HELP ME. I'm kind of freaking out because what if he got a little bit of on the outside of my vagina?
What should I do? Should I just not freak out, or what? Help!

How old are you ?

I'm 16... why?

You clearly need to take sex ed classes or at least pay more attention in them.

Yes, There is a chance. It is time that you have the sex talk with your parents or at least make a visit to the free clinic. Now that that's said. Sperm have one purpose, to fertilize the egg. Given that, they can and will get to that egg by any means. That's why you need to use a condom ANY time sperm is going to be released ANY where near you vagina. Yes, even in your under wear.
Do something for me go get an egg (from a chicken)and crack it on some under wear. Use two pair even to simulate what you just did. Does it seep through? Even the slightest bit. Yes it does. Sperm is very small and very present even before ejaculation. I hope this helps.
