My girlfriend has a problem with vaginal irritation during sex. The outermost part of her vagina is really sensitive and it doesn't take more than a few minutes (if that) for intercourse to become uncomfortable. We've tried using more lube but that just mutes any sensation she gets. We've been using Astroglide...is there something else we could try? I also use Trojans - is there another brand of condom that might not rub so much? I'm not sure it's the condom since she gets rubbed raw bareback too, but it's worth considering. L'il help?
