Hey Guys..been pumping for several years now. I have a question for those of you that have been pumping for a long time. I wanted to know if it is possible for pumping to cause some ED. I pump everyday for at least one hour. I have noticed that it I have a difficult time gaining and erection not while pumping. When we fool around (my Partner) I don't seem to be able to get past a semi/semi erection. If that makes any sense. Could all the pumping I do be the problem? Anyone else have this problem? Comments or suggestion ??????????????
