Recently, while I was in the interim of the action, my part lost its erection and since last 4 days i am not able to sustain an erection. I have got my blood
sugar and
testosterone levels checked which are absolutely normal. Vit d levels are very low.
I have no idea why this happened suddenly because I have never faced any performance issues in the past. Is there a possibility of muscle rupture ? Pls guide me on this problem.
