Arousal Gels

I use Durex Utopia. I tried it on the nipples, but it didn't respond at all. I think perhaps Arginine, the active ingredient that works by increasing blood flow to the area, doesn't absorb through normal skin. An arousal product with menthol or some other tingly feel thing is probably required for nipple stimulation.

Utopia is AMAZING on the clit and labia though!

I have never used them on my nipples, but I use them for my clit to get blood flow down there.
