Me and my girlfriend did dry humping 25 days ago. I was wearing my underwear and she was not wearing anything. Before doing so i ejaculated and cleaned my penis. But there was a wet patch on my underwear which touched her vagina while dry humping.

Hi, Anon.

Thank you for posting.

Firstly, the vagina is inside the body not outside. You can't get pregnant from dry humping. Clothing prevents genital to genital contact and ejaculation inside the vaginal canal. Many things such as stress, illness or a life style change can impact the menstrual cycle. Her period will come along in due time.
