Can You Get Pregnant From Dry Humping? - Expert Answer

Question
Hello there,
There is a BIG contradiction in this world!!!!
Me and my bf usually do dry humping, rather than sex.
lately, i saw online, over Google, a couple of people and websites that say that you can actually get pregnant from dry humping!! Is that true??
Now, i have my period, and today, my bf rubbed himself several times over my pants and panties until he came(away from me), then he rubbed himself only over my panties! Of course i was wearing a pad for my period, so i'm pretty sure NOTHING, no cum or precum, can pass through that, and up into my vagina to knock me up during my period.
I just want to make sure am i right or do i have to worry? or are these websites right?When can actually dry humping in the way i mentioned be a great risk for pregnancy???
thank you!

Answer
A woman can't get pregnant from dry humping.  For pregnancy to occur, it almost always requires the semen to be deposited inside the vagina.  It might be possible (but rare) to get pregnant if a man ejaculates on the outside of the vagina.  If the woman wears panties, and he rubs some semen on the panties, I don't think it's possible for that to cause a pregnancy.
