Presently I have lost interest in sex. This is because I have difficulty getting and maintaining an erection. Previously my libido and sexual desire were strong, but my erection was weak. My midnight erection and early morning erection is normal, and achieving and maintaining a daytime erection is very difficult. I can not penetrate. When I try to penetrate, I lose my erection. I have not done sexual intercourse yet. This is because I have lost interest in sex after marriage. I have no desire for sex, only desire for foreplay. I have a loss of libido and low sex drive. I love my wife, but I have no lust for her. I have no sexual attraction to her due to a lack of arousal, sexual stimulation, and sexual desire. My previous medications are Tentex Royal capsules, Popson tablets, Paternia XT tablets, ED save pills, Modula tablets, Tazzle 10 tablets, Tazzle 20 tablets, Canberra tablets, Penegra tablets, and Dejac-T tablets. Presently I am not taking any medications. I took testosterone, TSH, FSH, LH prolactin, and a penile doppler ultrasound. Please help.
