Hi. Well my girlfriend and I have a lot of sex and it is back to back and sometimes non stop. She says it starts to hurt later on during it like if it comes out and we try to put it back in. she say it is painfull, feels like it is swollen shut and ripped. She also complain about swollen glands down there? She say it burn when she pee after, but only cause she say it feel like it in a cut or something. We used lubricant to try to take away from the swelling that she talk about but it not work. Her mom telling her it somekind of infection or std. do you think you could help me out and tell me what some of this stuff is maybe like the swelling shut feeling, burning and all the gland things? If you could it would be a big help thanks

Slow down cowboy!! LOL

Women's vaginas are very tender tissues. She needs time to "recover" This hard and often very well could result in cystitis. At that point she would need to see a doctor for antibiotics.

Simply put, you are possibly injuring her vagina be having sex so often.
