Hi there.... i recently got a chance to get physically very intimate with my girl and noticed many interesting things......... one thing is her vagina was secreting some liquid from the very begining it was white and sticky. is it normal because it started even before we both became naked and the second thing is my penis got erected and once i tried inserting mine into hers my penis suddenly enlarged more and first time its tip became pink and the skin was streched behind the pink mass....... that kind of penis tip i had seen in porn but it was very new to experience on my own and it took quite long to come back to normal, i.e, for the skin to become loose and cover up the tip of my penis like in normal time.....due to these things v didnt have sex and i jus ejaculated in the bathroom........ please let me know is this wat happens while having sex......
