The boy puts his penis to the girls vagina but this is going to be the first so the body called hymen breaks and the vaginal walls widen and little to no blood comes out. That's it nothing new. The actual taking virginity thing comes in your mind. The thought of you making a girl let you put your penis inside her for the first time , letting her sheild down,her naked and vulnerable only with you is the huge ego boost. I have to admit you have achieved what many have tried and failed this is what makes you manly!
