No, sperm can't live outside the body. So by it getting on your stomach and sliding down wouldnt work. He would have to have ejaculated inside of you, and even if he did that still doesnt mean you would get pregnant, remember you can only get pregnant like two or three days out the month.
If Semen Falls On Stomach And If It Slides Down To Vagina.Are There Any Chances Of Getting Pregnant?
If the sperm stayed outside you body, then you cannot get pregnant.
There are only within 25% chances...Falling where isn't the matter....it must enter the vagina completely and the semen must merge with the partnes sperm....so it 'l lead pregnancy.....
