Do not be worried about some one seeing your vagina!
Well, his penius is going in your vagina. Like when you use a tampon it hurts.
Thanks for your help :) ..I don't think its that he's small because I can definitely feel him inside me I just don't have any sort of feeling it just feels uncomfortable down there and if we have sex for a long time it can start to feel slightly painful and my vagina can get a bit puffy I have a feeling he might be too big for me as we have to start off really slow and stuff to fully get him inside and that's the part that feels most uncomfortable. I was reading before that sometimes men can't break you in as you can have a strong vaginal wall or something like that and you have to go to the doctors/nurse and they can break it for you. I don't know what it is, oral sex is great!! but sex just doesn't do anything for me and I'm too embarrassed to go and see a doctor/nurse about it.
Your flora may be off in your vagina, with yeast overgrowth that is just not easy to see. It can ruin good sex. If you don't have good lubrication, this might be the culprit.
Or if your BF is too big, you may need to try different positions where you control how deep he can go.
You could possibly be you, and it could be your boyfriend. Maybe he does not do it the right way, or maybe he is to small. I'm not being mean, I'm just telling you what it could be. I know I lost my virginity to a virgin and we were together three years. I hated sex til I met my boyfriend I'm with now, and he is not at all small compaired to the others I've had sex with and he actually knows what he's doing. Very well. And now I lovee sex. Maybe you two should watch porn TOGETHER. So it doesn't become a habit, or anything. And try to do what they are doing to "learn" how to get the turn ons. You know what I mean?
