Hmm hmm hmm..How to respond? Do I stoop down to the name calling and petty inferences? Or do I take a more mature approach? I think i'll do the opposite of what you did and i'll take the mature approach.
I will admit that I know nothing of you or your relationship with your girlfriend. Instead, I must go with what you have provided me, and anyone else reading your post, about you and your relationship. What I got from your post was a very uninformed and naive view of women. Or maybe a better way to say it is a very immature view of women.
I agree with you that it is important from a health standard to know about your partner's sexual past, but I disagree with finding out whether your partner is a virgin simply to know if your partner is a "promiscuous person" as you so eloquently put it. For that reason, I believe its none of your business. You asked your girlfriend, she gave you her answer. But you weren't satisified so now here you are, on the internet graphically describing your girlfriend's genitals to strangers, trying to discern whether or not she is lying to you. That's sad. Where is the trust and feelings you claim to have for her? I think the things you said in your original post are very degrading and disrespectful to not only your girlfriend but to all women.
I seriously hope that you are young and will grow out of this immaturity. I hope that you will become more informed about women's bodies and learn that there are much much more important things about women and relationships with women than whether they are virgins or how many people they have been with.
Just to quickly comment on your sexually transmitted disease statement: a person can have intercourse with 30 different people and never get a sexually transmitted disease while another person can have oral sex with just one other person and contract an std without ever having actually slept with them. The number of people you have been with is not indicative of your sexual health. It is very naive and dangerous to think that.
