I'm a single woman of a certain age and don't feel that much in the way of sexual desire most of the time.I am on HRT and sometimes I get an overwhelming desire for an orgasm. It's a bit like an itch you can't scratch.Being on antidepressants means it's really difficult to get there so I am considering devices. The problem is they're all so noisy and I have an adult son in the next room.I wondered if anyone could recommend a vibrator that is actually silent or very low noise?
