If u have a lisp wat does that mean.?

It means that you need speech therapy. It has nothing to do with your sexual preferences.

speech therapy

A lisp is a speech impediment which mean
You can't pronounce certain sounds properly
Like ssss as in s.
It's not your sexuality

They are just saying that your pronunciation of certain or most words is unclear and maybe sound a little bit weird.

It means you have a speech impediment. It doesn't mean anything about your gender preferences, obviously.

It's when you can't say the letter S properly
