I'm a 23 year old virgin. Hire a prostitute?

I was very fat up until months ago until i did a gastric byp surgery. Of course, girls wouldn't want to have anything to do with me when I was huge, so I got very little ual experience and never had . This is something I want to get out of the way, because it bothers me and I need to have a first experience so I'm not so insecure when trying to get a girl. Girls are starting to notice me more and it scares me that at that age I could have difficulty knowing what to do. So maybe I shoud hire a hooker.
