My boyfriend and I were doing some things together. First, I gave him a hand job but he did not come. Then i gave him oral and he did not come for a while, and when he did, I spit the sperm into a tissue. after spitting it out, my hand was a little wet and my other hand was wet from the saliva and stuff that was on he penis before he comed. I touched many different things and even wiped my hands on pants, but did not wash them. About 45 minutes later, I went to the bathroom and did not wash my hands before wiping and may have touched my area but not the vagina hole. Is there any way I can get pregnant from this?
