I'm scared..:-(

My bf and I had dry sex 3 days ago.
He brought up the topic the next day.
It's kinda stupid that we didn't talked about it first, but we weren't thinking at that time.
I was wearing short shorts, underwear, and two panty liners overlapping each other.
My bf, on the other hand, had only his underwear and jogging pants/pajamas.
There was this one time when he brought out his penis and started poking around my vaginal area. I could feel it through my panty liner..
He doesn't know if he pre-cummed and that is making me paranoid right now.
I checked my clothing and panty liners if they were wet, but they were dry...*phew*
I also told him to check his clothing, too, and it was dry.
I'm just afraid about the time he brought out his penis. What if he pre-cummed and it got on my underwear? I know it only holds a little amount of sperm, but I'm still paranoid.

I want to know if its serious or not...

I really want my period right now so I don't have to worry about it...:-(
