no his penis did not touch just his hand...thanks a lot :)
Do you mean that he touched his penis to your vaginal lips or just his hand after touching his penis? It is possible if his penis did touch, but all the same, you've had two periods since this event. It's **highly unlikely** you are pregnant. Sometimes our cycles are just lighter due to differences in hormone levels and the like.
You cannot get pregnant from what you did, you would need to have had pentrative sex for that to happen. Diseases can stil be spread though. Something else is just making your cycles irregular, see your doctor if you're concerned.
