Hi, I'm completely new to this site , and I don't know i'm asking my question in a right forum or not. I'm 35 years old which had PMO for 12 years, I used to get erection with watch P and simulate my nipples , every time ! Now I realized I can not get an erection with normal simulation , and there must be nipple simulation to get an erection ( with the help of a 25mg sildenafil pill). ** I have some random morning woods , sometimes strong and sometimes weak. So , I realized my brain is rebalanced and decided to do NoFap , I did it for 21 days , it was awesome , and then I was in a sex situation with a partner , I was surprised , I came in 30 seconds just with touching !!! Than I was really depressed and try to PMO again for two weeks !! Again I decided to NoFap and did it for 14 days and try to have sex(with sildenafil pill) and I didn't get any erection(very weak and temporary) ! But still morning woods happen(sometimes). I think my problem is my mind which is not getting aroused !! I have mentally no libido , but sometimes high libido(few hours some days) , completely unstable libido , erection , arouse and desire !! I realized sometimes I'm not aroused even with my favorite Porns ! sometime very strong desire to them, really bad situation with no stable behavior make me worry and because of all these issues I got performance anxiety , every time I want to have sex I'm anxious and my armpits and my hand get wet because I'm always concern about my performance in bed. ** I have very random desire to the Porns categories , sometimes aroused by Transsexual categories , sometimes arouse by lesbian , sometimes with a straight categories. ** I do workouts and have a healthy life style , but it does not helped me at all ! I really appreatiate any help , suggestion or experience. Thank you.
