I am a 30 years old guy and i havn't had any full erections in my penis for past 3 days now before i always had normal erections and good sex drive. Now only when i try really hard to masturbate than my penis gets erect but that to about 65% at best and than i reach my climax also i woke up to an errection yesterday morning but was not able to do it properly when i am awake. My last proper erection was when i was having sex with my gf 3 days ago and was a bit worried about my performance and couldn't do it twice from than on i havn't had any proper erections. I am really stressed and am loosing my mind and am going crazy thinking about this issue and don't know what the problem really is and whom to discuss. Please can anyone give any suggestions or remedy to my problem?
