Unfortunately this same thing can happen if you go out for particularly long dance outings, for similar reasons of excessive stimulation. Most Friday night or weekend dances are 2.5-3 hours and I have been to special events as long as 4+ and this can get physically demanding. Having the urge can happen in this setting. And obviously it's awkward if you are going to be around hot girls. But there's no good solution for it so far - and of course these places also don't have showers at all as some gyms do. Best I can do is use cologne and have changes of clothes. I don't use coffee because it's at night and I don't want to be up all night. I don't want to use alcohol to calm down after because the sleep quality will be shite not to mention that arguably any alcohol use is a terrible long term choice. It's a conundrum...
