Genuine Question (Reposting, as I was suggested from a different subreddit)

Genuine Question

I’m 19f and bisexual, and I’ve seen a lot of posting about les4les and not wanting to have a female bisexual partner and I was just curious about the reasoning?

Is it genuinely about attraction and preference specifically toward lesbian women? Or is it some kind of defense mechanism against a partner who (in your mind) will potentially cheat or not be as invested in the relationship? For the second reason does it stem solely from personal experiences or those of others that you have heard about? Or maybe there’s another reason I haven’t heard yet, but I would love to learn more.

I know it’s a hot topic, and I’m definitely not trying to change anyone’s mind. I am only hoping for some genuine, thoughtful responses. Please try and keep responses both to each other and this post respectful, Thank you.
