Hello I am 19 yrs old and have been with my partner now for 2 and a half yrs I have never cheated on him and as far as I know he has never cheated on me. I have 1 child who is nearly 8 months old but whenever me and my partner have sex if he goes to deep it really hurts the back of my vagina, then when we are finished I get really bad pains deep inside me, the pains will normally last for 5 - 10 minutes I am worried it is chlymidia which means he would have cheated on me but more seriously I am worried it might be cancer could you please help me because I am really worried

Thank you kayleigh55

If you are that worried what exactly are you doing here why haven't you made an appointment with your dr??
I have to say its unikely to be cancer but never say never, he is obviously being to rough with you and bruising you. Slow down it's a sensative area.
Please do go see your dr though and explain the pain it could be a number of different things and you really shouldn't wait around to find out.

I had something similar myself, so I understand how you are feeling. In my case, it was simply that the mucus of the lining of my vagina had been worn away during sex causing this pain and a deperate need to go to the loo which was painful. Could this be the case for you? I remember I had bad pains deep inside and a feeling of pressure which just turned out to be minor swelling.

I have endometriosis and intercourse is painful for me. Maybe check into the symptoms of it or have a pelvic exam to ease your mind.
First of all, tell your partner to go easy until you find out what is going on.
Don't try to guess because you will drive yourself crazy. A lot of things have the same symptoms so don't wait around if it continues, ask a doctor for their opinion.
