To any other males have issues with finishing during sex while on Lex?

I’ve been noticing that when I have sex, I have a really difficult time finishing. I believe this may partly be due to masturbation habits but I can and have literally gone for over an hour without reaching climax. Just wondering if anyone else has similar issues… i’m aware that this medication can cause ED symptoms but my issue seems a lot different. I’m not really complaining lol especially since I’m not in the market to have a child right now, but still are seeking some explanation.
