If I indulge in too much pornography when I close my eyes at night all I can see are penises. It makes it hard to fall asleep. Am I doing bad things to my brain?
I am guessing that you are young. And maybe just have too much sex to get out of your system that is available to you. At any rate, if you are dreaming of penises and thus, perhaps you need to see more of the real thing other than your own. This is the 21st century. Everyone can adventure wherever they wish (just do it safely). Your job is to find out who you are.
