Secondly $€xual performance is the issue. I don't know where to look up for help regarding this issue. I posted here quite some time back but couldnt get any help.
I did see this older post; some pretty funny replies. And a couple of useful ones.
I have heard a lot that one should know about the plumbing. Are there any tips one might share for being better at it. What women like in bed? How do you satisfy them?
what about that do you think is the issue? there is a good number of very different guys on this forum, someone will know but you have to tell enough to give them something they can answer.
there is a lot of youtube video on the topic to tell about the mechanics of it all, as in what to do and how.
what specifically makes you think this is the issue?
there can be mental and or physical issues and one can cause the other. all of them can be improved; usually by a lot.
one thing you can do is date someone that is lower SMV than you and practice a lot. that way you will not be intimidated by them or worried about if they are impressed. then just have some fun; again and again and again...
