im 18 years old and so is my girlfriend. we have been dating for about nine months now. she is a virgin and she wants to lose it with me but shes worried that it will hurt. so what can i do to make sure i don't hurt her and make it a bad experience for her? my penis is exactly 7 inches long erect, is that too little, too much or just right, i just don't want to hurt her so any advice on what i should do will be helpful.
