I am a lesbian, and my girlfriend of two years is experiencing pain in her lymphnodes by her pelvic area, especially during sex. She is finding it hard to orgasm, and has to stop because of the pain. There is no swelling, just pain. What can this be?

When there are swollen lymphnodes it is a red flag for an infection in the body. Your friend should get blood work done with her GYN.

Since lymphnodes fight infection near the site of the disease in the initial stages, I would think your friend has some sort of infection in her sexorgans. That is just a guess.

Time for a visit to the obgyne.

A kidney or bladder infection has symptoms of bloody(usually) urine and pain in the lower back or in front in the bladder.

Some sort of problem in the lower intestines and colon is also a possibility.

Best wishes, :)
