I did a few cycles in my mid 20's and never really had much sex when I wasn't on cycle. I never did proper PCT. But I've noticed that having sex off cycle now, I don't get nearly as hard and it's almost impossible to not pull the trigger way before I want to. Like 1 min in. When I'm on cycle, I can jackhammer them for an hour and not finish unless I want to. Has anyone else noticed this? I'm not sure if it's low T off cycle? Or some ratio of test to estrogen? I have noticed when estrogen goes up, it's similar to being off cycle.
