When I was 18 I joined the Royal Navy. Every morning you could hear the other guys wanking. It was a morning ritual. Nobody openly admitted they did it, it just used to start.
Occasionally the lads would shout over to each other that they had heard the stifled grunts of another lad cumming. I always wanked dry by laying on my front and rubbing my cock slowly on the mattress using small moves. I also had a bottom bunk, but some of the lads obviously used lube and you could hear the rhythmic squelching. That used to really turn me on.
When we showered you could see that many of the lads had just had a wank by their swollen heads and retracted foreskins. This really turned me on also, though through will power I managed not to get hard in front of the other lads and used to go to the heads to have a second wank. It was equally erotic to see the lads who had not jimmied off walk around with an obvious boner in their shorts.
I am not gay and have two beautiful sons and a lovely wife. I have left the armed forces and am a civilian now. I do not know what it was, but the sight of loads of hairy cocks on a morning turned all the men onto the point that I even let one of the lower ranks give me a hand job in the head. My rank is CMDR. I think that letting another man wank you off is not all that gay, it is just an expression of sexuality in itself. Everybody is horny at 18 and most will do anything to spend their wad! That said, I wish I had taken the opportunity to gain more experience with other men in the navy as when I read your website I feel as though I have missed some chances to do what is obviously normal!
