I was just sitting outside the back of my house, not aroused or stimulated in any way. Suddenly felt a wetness and something leaking out of my penis. Went to the bathroom to check, and it was semen...
No idea how this happened, or if it's even normal!
I am a 24yo male, having regular sex with my husband, plus masturbation. I have no STDs or anything like that, as I get tested regularly. Even got tested for HIV just recently too, and I'm all clear. We always use protection and clean ourselves properly, if that helps.
What could it be? It wasn't a full amount of fluid, but it was quite a bit nonetheless!
