Baby oil may destroy the condom before you are even done having sex, these sorts of produts should never be used as a lube. You can get good quality lubes like Astroglide or ID or whatever will be better. However, if you put lube over your dick, then put the condom on, and then try to have sex, you risk the condom slipping off inside the girl. I know from expereince...

Luckily it did not happen with a P4P girl.
The condom indeed may come off faster, but I think the risks are too high.
You can test different ways by using a condom when you masturbate and see what works better for you. Have watched a lot of porn movies also, they just take the top of the condom and pull it down off their cock fast before shooting their load.
