Suggest Treatment For Erectile Dysfunction

Hi I m 21 years old, my weight is 110 kgs and height is 6 feet 2 inches. I have been facing erectile dysfunction, while making love to my partner. Initially I find it difficult to get erected with condoms but in between I got comfortable. Recently we changed the brand of our condoms and since then I have been facing erectile dysfunction normally as well. Also, I feel that there is something flowing out of my penis, when it is not erected. I tried last night to erect I was able to keep my erection for more than five minutes, but when I tried after an hour I couldn t get to the complete level of erection. In the morning I tried to check my erection, though it led to masturbation, I didn t get completely erected. Kindly help.
