I go to a nude beach a couple times a year in the summers (Mazo Beach, in Wisconsin). Jacking off on the beach would very much be unappreciated by the crowd there, as would be a flagrant erection.

But off to one end of the beach is this tall grass area, and there is always a guy or two there jacking off. In the water it happens as well. I've jacked off and jacked or fingered others in the water. Of course, I've done that at normal beaches, too

Usually it is after a day in the sun and wind, once we get home, that the real fun begins since no one wants to put their clothes back on.

I always spend most of my time at a nude beach in the sea. I cant help but get a real stiff erection looking at everyone else nude. I love jerking off slowly in the sea, sometimes stood on the bottom looking up through the water at any nude bodies swimming around above me while wearing a face mask or goggles.I normally shoot my load around 3 times in a day doing that.

I can't imagine being at a nude beach, on a nice day and NOT jacking off at least once...

I used to visit a nude beach 2 or 3 times a summer for about 2 years. It was very hot because this beach had a place where you would go if you were looking for more than a tan. I saw lots of jacking and joind in a few times. I also saw lots of sucking and even a few fucks. All male but there were plenty of hotties on the beach to fantasise over. Very hot!!

There aren't any legal nude beaches on the Texas Gulf shores. However, there are many secluded areas where naked masturbators can often be found--me included. Last week I was enjoying myself at one when a guy pulled up near my car. I had a porn magazine propped up on the steering wheel and thoroughly enjoying it. He got out of his vehicle and came up to watch. I had him take a few photos, got out of my car and asked him to shoot a full body shot. Then I shot a nice load. Unfortunately the pictures he too did not turn out well and I had to delete them.

I did once many years ago in Vancouver at Wreck Beach.
Because I did not know the proper rules of the beach, I hid back in the bushes, and peeped over a log while masturbating to ejaculation.
Was very exciting, and would love to do it again some day.

I go to Lucy Vincent Beach on Martha's Vineyard. I've seen cock rings and hand jobs, but never oral sex on the beach. Most of the men are over 50 years of age.

I like to ejaculate for female gawkers, sometimes I will masturbate for a particular female gawker, sometimes I can ejaculate without masturbating and it is only half hard, when I masturbate I can shoot a big load about 10'. I really like when there is a group of female gawkers who slowly walk by staring at my cock.

Fucking hell bubbaloooey, that's so hot! I love wanking naked with my legs spread wide apart and shooting my load all over the sand, but I've never plucked up the courage to do it in front of females in case I get arrested. But cumming for a group of girls is one of my all-time favourite fantasies, and that post just made me rock hard (especially the bit about cumming half-hard, for some reason that just feels so good!).

I have not really attended a "nude beach" but have been members of several nudist resorts with both my 1st and 2nd wives, and later with my 2nd wife's sister.
Public sex is highly frowned on, but covert sex by couples certainly does occur. My wife and I and another couple were in the privacy of our camping site, and the other wife commented on the size and shape of my cock, and asked her husband if he would think she could look or touch it. He said that he better ask my wife or better, ask me herself.
My wife said, "sure, go for it, but I get to play with your hubbies cock too". They both played with the other guys rock hard cocks, but we all decided to retire to our own tents and filling our wives with the other woman's partially excited hardon. After we had cum in our own wives, we all went to the pool to recover.
My wife passed away in 2006, and since then I have spent many sessions with my sister in law, and we joined another nudist resort in Florida.
Several times, in the privacy by ourselves, Sis has reached over and jerked me off and swallowed my load rather than spilling out my load.
