Possibility of being pregnant with no ejaculation but dry humping (penis touching mostly towards top of vigina near clit) ?

Pregnancy chance: You are not very likely to get pregnant if there was no exchange of fluids. You can however get certain STD's such as Herpes doing what you described

Unlikely: Best to use condom even with "dry humping" If worried can 2 pregnancy test on first morning urine 2 weeks after sex. If negative, repeat in 2 weeks. If both neg, highly unlikely you are pregnant. Hope this helps. Best of luck. Dr R
