I'm not a lesbian, I have no "hormonal" issues (aside from the normal conditions associated with perimenopause) but my husband and I use dildos and phallic vibrators because he can't be in two places at once
for one. I like vaginal penetration during oral sex, he often uses his hand, but sometimes we use a phallic toy instead. Also, during DP, when his penis is in the back door, we use a dildo in the vagina for extra fun. He also likes for my to put them in my mouth for his pleasure.
I can't even believe anyone would be astounded that any women, straight or lesbian, would use sex toys. They have many uses and are a lot of fun.
It has NOTHING to do with being "sexually assaulted" nor hormone disorders
, it's simply a fun thing to add to already fun sex. It's often not "instead" of a penis, it's in addition to one. Two are often better than one, and bringing a phallic sex toy into the bedroom will cause a lot less drama than bringing an other penis with an other person (and their needs) attached to it. Dildos ask for nothing and don't mind being put aside when you aren't using them.
