Weird Personality Change?!?!?

This is going to sound very strange, but please give serious answers!

Whenever I'm around my friends, I'm very very funny.

But not the type of funny I would like to be, when I'm ';funny'; I get sexual and gross

Most people think this is funny, because its coming out of MY mouth

I really want to stop being this way, and I've tried REALLY hard, but every time I try to be ';funny'; I get all weird and gross! How do I change my sense of humor?! Because I know most people hate others with a gross/weird/sexual sense of humor. I don't want to grow up and be like this ALL the time, how do I change my ways!? I honestly don't know how to be funny without being gross

How else are people funny?! PLEASE HELP!!!Weird Personality Change?!?!?
I totally know what you mean!! Lot of people thought i was weird and they didn't talk me because of it. I just tried to tone it down, like not really sexual/gross and then it came to me to become funny-funnyWeird Personality Change?!?!?
