What martial art would fit for a former wrestler?

i just finished up with my high school wrestling career, but i still have the need for competition i never was really involved with martial arts so i don't know witch one to pick. i want one that has both the stand up and the ground game like wrestling but different. One class i will not do is Brazilian Jujitsu because if i do all my friends will wanna fight me, and that's what im trying to do. Thanks
