Hey there last night me and a female friend wanted to have sex but I did not manage to get an erection. I had this issue around three weeks ago in October (however the erection disappeared after putting the condom on). What I now noticed is that I am not horny at all and absolutely don't feel like doing something sexual. Is this already the flatline period? I read that it usually starts three weeks in so I am a bit worried that something is wrong. I know I mustn't watch porn in order to find out if my dick is still working and I don't have the intention of doing that (don't even feel like it tbh). However I need some guidance because I feel like a headless chicken at the moment. How long does it take? Should I take viagro or similar stuff when this happens again? Can I do something to speed up the process? Cheers for any responses!
