Almost 200days close friends gone no relationships

I used to be tight with all my buddies but i have always been a shy guy around my friends and girls. I was never one to talk about the girls with the guys cause i havent been with many. One of my good friends growing up after highschool came out that he was gay. This really took a toll on me never in my life would i guess he was gay. I was embarrassed that i was even friends with him. I dont speak with him anymore, and what upsets me is people knew that i was friends with this kid and i havent had a girlfriend in years, i get the feeling from some of my other friends and even family think that i am gay just because my friend was and i havent had a girlfriend in years. Been almost 4 years since i have had sex and the last time i did i couldnt get off it was a bad situation. All my friends found out about it and it made it worse. I decided to start NoFap and im very disciplined person and have almost reached 200 days but havent gained much confidence because i dont talk to my friends much anymore because im afraid there going to ask were my girlfriend is or who im having sex with i have no answer. Same for my family. Im shy and would like to get out more but its hard for me and also to do it by myself. Please help
