I've been on Suboxone for about 15 months and ever since then I've had erection problems. It's difficult to achieve full erection and it's difficult to remain hard. I'm pretty sure this is because of the Suboxone but I'm not entirely sure. I don't remember this happening before the Suboxone but I'm kind of worried it could be something else. All my veins have collapsed from IV heroin and other drug use so maybe that could have something to do with it. I've looked online and can not find much about other Suboxone patients having this problem, so I was wondering if anyone has any information on this issue that can help me out. Thanks.
