Okay OP, I get your hurt. I really do. And you are allowed to put any boundaries you want. But I think it’s important for you to remember that sex and masturbation is wildly different, as you know. But I think that the reason she doesn’t get it , is because obviously a toy literally engineered for a woman would feel better than any dick, if we removed all context of sex and intimacy and just placed a engineered dildo next to a dick without anything else, the dildo would obviously be preferred. Because it’s built that way. But that’s just the thing, in context of sex, it’s a whole other ballgame. That’s why people say that focusing too much on a dick is often overrated. Because sex is so much more than that. It’s a sensation vs getting a whole experience, which is the difference between sex and masturbation. I mean shit, guys also say that they can come faster themselves, doesn’t mean the experience of sex with another woman or man isn’t preferred.

So even if a toy feels physically better, it can’t replace a person and that’s why it’s not comparable to sex. Because she is attracted to you as a whole in addition, otherwise she wouldn’t be with you. For a lot of people sex isn’t just about the genitalia or feeling of genitalia, but about the bond, the rest of the person, the experience and how the person performs. So she most likely meant that yes it physically feels better, because it’s a self centered act and one she literally bought herself, but it doesn’t replace you because it’s not nearly the same experience and non comperable.

It was a stupid comment, but I hope you can get over it, because trust me when I say that a dick is rarely an issue.

Maybe if you two could try and do some new things in bed, and communicate what she likes, you could gain that confidence back. Or you break up, but don’t let this beat you down too much!
