Shower Head
I find it odd that only women ever submit techniques involving shower heads, I love using them!
When I'm in the shower I spread my legs (while standing) and put the shower head just under my ass and pointing up so it's spraying just behind my balls and then I start giving my penis long slow strokes
I do that until the pressure builds too much and I can't take it any more and then I put the shower head directly on the back side of my balls and start stroking like crazy
I get the most intense orgasm ever with this and I shoot cum everywhere!
