[|Human|] hi, i am a 21year old male and have been suffering with cystitis since 8yrs old, i drink lots of water and cranberry juice and do not suffer from it when urinating.since being sexually active i have started getting the same pain a cystitis but after ejaculation. i do not get the pain during sex or whilst i am ejaculating, only after. i am then on the loo for up to an hour drinking water to flush it through. i have been to the doctors several times with the same problem but am getting nowhere.
[|AI|]  HelloThanks for query. During erection and sexual intercourse the blood supply to penis is increased to many fold resulting in congestion of entire urethra. This congestion remains for a 30-45 minutes and gradually fades away.since you had established chronic infection in bladder the pain that you have after ejaculation is due to this persistent congestion of urethra. You need to Chat Doctor. This will help to resolve the problem.
