Accidentally stimulates myself with woman's lube, will it affect me in any way?

If you’re worried that the KY has some special “female-based” ingredients that might damage you, the answer is no; it is possible that your penis may have a skin reaction, but that’s not because of the lube being ‘for her’ – I t’s because the penis skin is VERY sensitive, and there could conceivably be something in the ingredients that you particular penis has a reaction to – but even that is unlikely. A better choice, of course, is to use a special penis health cream (health professionals recommend Man1 Man Oil) that can also do the job of providing important vitamnins (such as A and B5) and nutrients (such as L-arginine) to your penis.
