I don't know about fingering but petroleum jelly and baby oil can both damage or weaken a latex condom. Why not use a product that is specifically made for sexual lubrication? KY, Astroglide and Wet are a few well known products.
I'm a female- sorry for trespassing- but felt the need to respond in case the fingering leads to something more and a condom is necessary.
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
Don't use any of those : they lubricate but are NOT sexual lubricants. Please use a waterbased (preferably sugar free, if your partner is diabetic) lubricant- can be bought anywhere (department store, drug store or sex shop). $7 - $20 - better to invest ;)Plus that way, it's condom compatible and you can go beyond fingering (if desired)
