Possible?

Okay so I recently went up to my boyfriend’s college to visit him. Annnddddd things got a little bit dirty. I gave him a blowjob and he came & we cleaned up and everything. Afterwards, we laid down and then went out to eat. When we got back (about two hours after he came), we began to do stuff again. We got very close to having sex but we decided against it due to morals but it was so tempting. He had precum and he didn’t pee after he came the first time & I was wet too... He teased me a little bit by sticking the tip towards the opening of my vagina and his precum sort of mixed with my secretions or whatever terms you would like to use. I absolutely do not think that I would be pregnant but I just want to ease my mind. Since he did not enter me, can precum get you/ myself in this situation pregnant considering he didn’t pee 2 hours before (when he came last)? Is there still sperm in precum if you haven’t peed since you last came?
