how to be less shy towards guys

I've always been shy when it comes to people, and it sucks worse when you don't fit the eccentric, outgoing personality everyone thinks gays of to be (and being in college for a year and not being with any guys) (and top it w/ 1.5 years of depression from bullying of my "friends").Anyways, I just want to know what I can do to begin being close & comfortable w/ a guy (even just ones I meet on Grindr lol). Any & all tips would be helpful!!!
