I know that many people, both male and female make sounds when they orgasm. I am not sure if that is automatic or done for show.

As a boy, I never made any sounds when wanking; possibly because I didn't want anyone to know I was doing it.

As an adult I haven't normally made any sounds when doing solo wanking; I just take pleasure from the feeling of getting there and feeling the joy of that last thirty seconds. Even when fucking, I don't remember making a verbal occasion of my orgasm; although most of the females I have been with have done so. Do females have a stronger sensation at orgasm? With one particular female I used to wonder if she would bring the paint off the ceiling!
