"I love butch women because no one else would ever have reached into that flannel-clad bundle of inarticulate erotic yearning with a mirror that reflected a sex goddess... I felt my sexual effect for the first time, and grew and grew like Alice in Wonderland drinking her magic potion."
I decided that even if my relationship ended, I'd never sleep with her.
I like toys because they feel good. It has nothing to do with whether my partner is good enough. I love fingering, eating out, and all the wonderful things that two women can do together. However, in order for me to be satisfied, I need a good pounding with a dildo every once in a while. Whether it's strapped to her groin or held in her hand, it's something that we both enjoy in our sex life.
On a related note, I've heard lesbians say that they don't understand strap-on sex because it's the same thing as having sex with a man, and women who want that should go get "the real thing." Of course, it's not the same. That statement is as ridiculous as saying that a man going down on a woman, is the same as a woman going down on a woman. Liking sex toys doesn't mean that I'm not a full-on homo, nor does it mean that my girlfriend can't satisfy me. These misconceptions are keeping many lesbians from having better sex lives.
Some people don't like toys, and that's okay. Some people do, and those people shouldn't be shamed for it. The stigma surrounding sex toys can make some women afraid to ask for what they want, which leads to mediocre sex. It also prevents people from trying new things, and ignores the fact that some women see their cock as a part of them. For those women, strap on sex is "the real thing," and for all lesbians who enjoy it, it's definitely not a substitute for hetero intercourse. It's a new world on it's own.
My girlfriend isn't trans (obviously, or she'd be my boyfriend), but as a butch woman, she sees her cock as an extension of herself. I do, too. I don't want her to put on a strap on because she isn't good in bed. In fact, it's the opposite. If she wasn't good in bed, I wouldn't want her to put on a strap on. Even when she isn't using her cock, we still like using other toys sometimes. Vibrators are fun, and so are dildos that wouldn't work with a harness. Other times, we don't use toys. We use our bodies to bring each other pleasure. It depends on what we feel like doing that day.
If you're intimidated by your girlfriend's love for sex toys, know that it has nothing to do with your ability as a lover. In fact, it's a good thing that she shared this with you. It means that she trusts you enough to open up about what she wants, and she's passionate enough about your sex life to try new things. Let me repeat that: she wants to experiment with sex toys because she thinks it would be fun, not because she thinks you're horrible in bed. She probably thinks you're great in bed, and would be even more turned on if you were willing to try something new. If it's something you're comfortable with, then try it out.
Life is too short to worry about social stigma, especially when it comes to what two people do in private.
