I think I have varicocele

Hello

I believe I have varicocele. I think it happened when I was younger (10) and now I can see my left one is larger and has the worm filled feel. Thing is I don’t want to go to the doctor for it because I don’t feel comfortable. I know that once they find out I have varicocele they’re going to ask for a semen analysis and no way in hell am I doing that. Just the thought of explain it to my family makes my heart drop. The semen analysis is the main reason I don’t wanna do it but honestly it doesn’t hurt or anything is it fine to just leave it alone? I have an ultra sound appointment coming up but I think I’m going to cancel it.
