Troubles adjusting..

(M20-something) I'm having some troubles figuring myself out.. I was in a LTR with a girl for about 4 years, it was my first sexual relationship. During the first few years I enjoyed it, yet I found myself not as satisfied as I felt I should have been. I have had thoughts and urges for guys since high school and I tried to ignore it. I told my ex about this and it was a means to an end in some ways. She was supportive, but became judgmental and hostile about it when angry. As a result I was ashamed of it for the year after our breakup and have just recently started to accept it and have told most of my close friends. Thing is, I have never been with a guy. I don't want a hook up thing, and I'm way too anxious to use dating apps/sites. I'm okay with whatever I like, but I don't exactly have a way of exploring my interests. Any advice?
