Question about hook up apps and if I should use them

Long story short I am skinny-fat, depressed and I have no social skills at all. I am 26 and have made out with someone twice a couple years ago, and that is all the physical intimacy I have ever had. I am desperate for physical intimacy. Does it make sense for me to try an app like Grindr or something? Is that a bad idea? Do you need to be really attractive or have really good social skills to succeed even there?Thanks
