Pregnancy scare

I hooked up with someone from bumble..well, sort of..we got high and I was basically a vegetable. I don't do it so often so when I smoked I got reeeally really stoned. Long story short..he came on my boobs but before that part he fingered me and I'm concerned that Pre cum could've been in his fingers when he fingered me? He was touching himself before then and I iterated before everything that I don't like to do anything sexual when I'm stoned because I feel like you can't really consent.
