Okay, me and my girlfriend were 'dry humping' naked and just messing about and my penis slipped in for literally like a second and was pulled out instantly there was no ejaculate or pre-ejaculate, I'm just so worried, what are the chances? Cheers.
Hi John,
Your chances are very low but they do exist. We can't give odds as there are too many variables.
I think "very unlikely."
Hope it helps.
