Sorry guys, it's look funny, but is serius, i want to know whats going on in the night...
I find an easy way, i drink a lot of water before sleep, and i wake up in the middle of the night to go to the bathrom, yesterday i got 2 night erections, but now i can understand whats going on, it happend after a dream, when i wake up i can see the diference, but it wasn't a 100% erection, it was like 70% or 80%, is something wrong? I think that im going to check my levels...
