Curiosity about wrestling leading to humping and orgasm. Unintended beginnings.

Just a scenario I've like all my life. Same sex usually. But anything involving wrestling.

Years ago I met a few ex wrestlers on Craigslist who were into total domination/submission wrestling. We didn’t discuss humping, erections, etc., but eventually it happens when your hands are all over your opponent and you’re being dragged on floor matts wearing nylon thin singlets. One of my opponents used several illegal holds as a distraction to get an advantage and dominate. Some of those moves caused erections and once a spontaneous orgasm.
