A woman has said that surgery for incontinence left her unable to have sex with her partner because her vagina ‘bit’ his penis. Theresa Bartram, 50, had the operation to lift her bladder using a plastic mesh, but it was fitted too low and eroded through her vaginal wall. Mrs Bartram, from Brighton, said that she had not had sex for seven years until she had the operation that involved the use of a plastic mesh sling called a transvaginal tape (TVT) to stop her leaking. She said that the sex was better until two years later in 2009. She said: ‘It was like it had grown teeth. His willy was bright red and spouting blood. There was a big red stain spreading between us on the sheets.
