About 6 months ago, I did a 10 week cycle of sustanon. In the last year I have found that I don't get aroused as easily. Now it isn't as easy to get an erection as it used to be. The hardest part, though, is keeping one once I have it. I thought about seeing a doc, but I don't have insurance. I could order liquid viagra online, but I don't want to become dependent on it for the rest of my life. My girlfriend is very hot, and I should not have any problem with getting in the mood for her. Some of it may be in my head, but I think I am still way too young for this problem. By the way, I'm 23 years old. Any suggestions?
