Me and my boyfriend were fooling around and I gave him a ha****b and he came and I wiped a little bit on my thigh but then rubbed it in till it dried and then put jeans on and I had a little on my hand and it dried and then we cuddled for a good ten minutes and he fingered me but he didn't have any cum on his fingers but I touched my vagina with my fingers which were dry but have previously touched cum could I be pregnant
