Men Moaning During Sex. Hot or Not ?

Men are usually the quieter sex in bed. Personally, I only moan briefly when my cock is throbbing and cumming hard and even then I'm still quieter that my female partners.

The exception to this is when I'm being pegged or my prostate stimulated. I could moan loudly in ecstasy for nearly an hour, I swear even my neighbour could here me. ? Is it something about being penetrated that makes men more vocal during sex? Thoughts?
