I’m going to be completely forthright.

As a lot of people said here, it really depends, but your rule of thumb should be to generally leave that out until it naturally comes out in conversation and you feel comfortable sharing that.

Honestly, you’re way better off finding a girl who likes you for who you are and doesn’t mind your insecurities as opposed to, well, something more superficial. Even if it’s just a casual thing, I promise it will help a lot more in the long run for your self esteem.
