getting erect sometimes happens. and I am so happy to say this still happens with me. in a public situation I choose a balance between enjoying this wonderful sensation and honoring what boundaries may be present in the place where this is happening.
A massage therapist once told me - Don't be embarrassed if you get an erection during the massage, it is normal, it happens all the time and - in a way - it is a confirmation to me that I am doing a good job (although the purpose of the massage was not to create arousal) ...
I get erections when i am really relaxed. I often get them as i am falling asleep at night. Not every erection is a sexual erection that means you want to have sex. I frequently get them when i have naked with my mates. They get them too. We neither obsess about them nor do we pretend they don't exist.
I don't think it should matter , I have noticed that I get erections for all kinds of reasonsIf I was hanging out naked with another guy and he got an erection I would take it as acompliment and would probably say something like, "lovely cock " and I've always foundif I've ever got an erection around another guy they have always complimented meor in a few cases decided to have a fondle or go further, we are naked men and we should bebe proud of our bodies and the fact that we can get erections, in later life they mightnot be so able to achieve, without viagra, what a great discovery !
A few years ago, I was at a naked pool party. One guy was putting sunscreen on his partner's back, and started to get an erection. He was clearly embarrassed and started to blush. One of the onlookers joked, "Should we leave you two alone for a little bit?" and another just commented "Nice one!" The erection was acknowledged and some mild teasing happened, but I think it was better to acknowledge it than to pretend like it didn't happen. The guy lost his hard-on after a couple of minutes, and the party went on.
Erections happen, sometimes when we don't want them. Shouldn't be a big deal or cause for shame.
