Okay so I've started to do injectable steroids and I have a partner and I am able to still **** and get hard, however whenever I pull out to switch positions and if I pull for longer then 20 seconds my one is begins to go down. However today I began to feel my penis not get hard while I was engaging in sex. Do I have a sterile ****? Is this serious? This is the first time it's gone down completely while engaging in sex. If anyone can help and tell me what's wrong I would appreciate it!
