Hi, I am a 36 year old male, about 1.72metres tall, weighing about 78kgs. One evening while having sex with my girlfriend, I lost my erection all of a sudden and from that day on I dont get easily aroused and if I do, I dont get the same hard erections I used to get before that day and I can't seem to hold the erection for long and sex has become a chore. I dont enjoy much nor do I crave it as much as i did. My penis is now softer than usual when flaccid and I've also noticed the need to go to the bathroom increased quite a bit especially just after the inccident. Please help!
