Dear doctors around, I and my girlfriend started having a little foreplay and that went on a little deep without us knowing. Both of us were wet, (I had my pre-cum & she had her white discharge) and she was drowning in fact.. when I was just on top of her accidentally my penis tip (half the size) went inside her and immediately I took it out in fear.. just 3seconds if I'm not wrong.. This was exactly the third day after she ended up her period cycle of the month. I masturbated the same day morning and made sure I cleaned myself fine. We now have a fear that she might get pregnant.. can you help us with our fear??
