PLEASE HELP ME, i suffer from anxiety and this is killing me!😞

I got my last period in the begining of September.

I wanna mention first that I am a virgin.

1) While i was on my period i went out with my boyfriend and we just hang out as normal, nothing more than kissing, hugs, and he grabbing my thighs.

I was scared that maybe he masturbated before going out with me and didn’t wash his hands and then when we went out he touched my thighs and maybe some sperm went in through my underwear&pad.

We have always done this and I’ve never thought anything of it.

2) I have this crazy obsession going inside my head and it’s causing me more&more anxiety. I am afraid of shaking hands with guys and stuff. Just two days ago I was out at school with a class-friend, and i was driving. While driving we were talking, so i couldn’t see what he was doing in the front seat. I highly doubt he would do anything with his hands but i got this thought that maybe somehow, HIM, before meeting with me, masturbating and then somehow have sperm in his hands. Just after a 40 minutes drive, we arrived and we said goodbye to each other by shaking hands. I shook his hand, and i dont know if there was anything but it was dry. 30 minutes after I arrived home i totally forgot that I haven’t washed my hands and i touched myself down there.

I stopped as soon as I realized and i went crazy cause it was supposed to be the day of my ovulation.

I am so scared that I’ll end up pregnant.

I dont know what should I do. I’ve been having a pregnancy scare nearly 3 months before and since then I’ve been going crazy every month and everytime i have a contact with a man.

Please please be honest. I would appreciate it a lot. Is there a chance i can end up pregnant by either 1) or 2) situation???
