I have been working out for quite sometime, but really over the last year been jooging a mile or two three days a week. I have always wore loosefit boxers while working out, never had an issue before. Latley, I have had trouble at times getting or keeping an erection while with my girlfriend or by myself, which has never happended before. Does anyone know if there my be some correlation here? I am hoping my switch to boxer/briefs for more support will help with this. Please Advise!
