Normally I'd say no, but I've heard of lesbians using double-sided dildos, so idk. In the end, if you find your partner attractive, charming, and squirmy enough, does it really matter?
It's never mattered to nya, I just find 'is it gay' jokes funny, mew. Personally I prefer my toys with those curvy lumps, but mew will take anyone if theyr'e fun enough
