In my previous relationship, I wasn't able to keep an erection for a long time and I was majorly out of shape. There were other factors such as anxiety, stressed in the relationship. Now that I've moved on and have been taking myself seriously I noticed that I've been able to keep an erection for a longer period of time and was wondering if body health is Direct related to this. I'm still stressed and have a bit of anxiety the only difference is my health.
