ED in sex clubs when trying to have sex in busy playrooms

I’ve had my fair share of ED since I started having sex at 23. This resulted in me having sex mostly without protection because the moment I stop to put a condom on the erection is gone. Recently I found out that viagra helps and that normal condoms were too narrow for me and that getting custom sized ones definitely helped a bit.

However, I started going to sex clubs recently out of curiosity and with some female friends, but even when trying sex with viagra, I couldn’t get hard at all, and getting a handjob I didn’t manage to cum, which I normally can do with handjobs. Is there something in the brain preventing erections because i’m surrounded by many other people having sex at the same time? And how to overcome this? This now created a new fear in me that if I would go with a girl or meet a girl there and try to have sex and can’t get it up, they will just go find someone else, which in this scenario is kind of realistic, but very humiliating. What can I do!
