Well, the reason my doctor recommended it is because i've been having problems with irritation so he thought vitamin e oil as a substitution for ky would be helpful. However, I don't think that using ky was contributing to the problem, so i'll probably use that instead and use regular condoms. Thank you for the advice though. I knew in the back of my head that oil-based lubricants aren't compatible with latex condoms but for some reason that slipped my mind. I know I already asked this question, but do you think the fact that I did once should be a concern? I don't feel any irritation or anything. Thanks!
