To be honest - I did once when I ran out of lubricant. So my recommendation has a scientific foundation :P
If you're into a bit of SM, maybe you'll like it. But nothing for the faint-hearted.
Just a tip: If you want to have sex when water is involved, use silicon oil-based stuff which is not harming condoms. Don't use vaseline or grease-based lubricant with condoms - they'll tear.
That's fucking weird, guys! I don't recommend to try that at home.
The burning Sensation will kill you :D
