I would not be keen to masturbate outdoors unless it was safe.
However, in a safe environment I would love to. My first time with someone else was a mate and we didn't acheive penetration so we wanked ourselves and I have always wanted to wank in the pany of others since.
It would be especially nice if there was a female or two as well, I've always wanted to watch a woman masturbate.
Even though I don't live in Sydney I do get down there from time to time.
