Can Sperm survive in a bath?

I was.... masturbating in the bathtub with water in it (about 105 degrees). I pretty much just got on me, but I wasn't sure if it might've gotten into the water or not. So I got out, cleaned my self up, and I let most of it drain. Then 10 minutes later, I didn't know, but my mom took a bath. Shes like 51 i believe, but I'm still very worried, could she be pregnant?

Hi!
Don't worry--its extremely unlikely for anything like that to happen--pretty close if not impossible.
Good luck!
