First, I'm sure the man's Penis was of average dimensions & proportion ; your lack of experience is just speaking there, justifying your surprise. Second, many Men including myself have quantitatively done enough favors for girls introducing them to womanhood. i.e. it becomes too much of a chore, knowing how much a girl will remember her first & the necessary consideration involved etc.. Third, you most likely for some stupid reason, shave your vulva, mons pubis, etc. making the optics of it unattractive & less visually arousing. I only need to know the little you have revealed coupled with your choice of words & writing style to categorize you. Add your average appearance to conclude it is lille wonder you are still a virgin.
