Do recurrent bouts of cystitis spell the end for my sex life?

My doctor gave me antibiotics, which I take every time it flares up (once a month) and my boyfriend is understanding, but it makes me less keen to have sex because I know that the more sex I have, the more it aggravates it. Is my sex life ruined forever?
If you haven’t already done so you should get your GP to refer you to a urologist and you should also get yourself checked out at a sexual health clinic.
