Baby oil has more chemicals and perfumes that could irritate the skin....but petroluem jelly has worked the best for my hubby...
hes not gay but we do like to experiment. He will only use jelly..I personally like it a lot to.
They have anal lubes at the sex shops...that are specifically designed for anal sex/anal play. I have also found that the thicker lubes work better w/anal play and the thinner work better for masturbation and vagina play
