I don't know if it's mental, or whatever it may be..maybe my lack of sleep as of late (lil bit of insomnia)
If i'm sexing a girl, i have no problem getting hard for a bj, but about halfway thru penetration, i go limp. I end up laying there, and in a while i can go again. It really sucks, because i cant stay hard as i want. It's like i just lose my sex drive, or it's all mental. Maybe my libido is shot because i dont sleep good anymore
maybe i'm just thinking too much.
