My husband is 41 years old and has been taking oxycontin for the past 4 years for cronic pain/pain management.  We have been married 17 years and have always had a healthy sex life.  Recently things have changed.  We have sex only once to twice a month at most.  He is having trouble getting/maintaining an erection and is also having trouble with premature ejaculation if we get that far.  We have never had any of these problems in the past.  I was looking for some answers on the web and found that possibly the long term oxycontin use has caused lower testosterone levels.  Could this be a cause?  Should I ask him to have these levels checked?  I am not sure how to approach this VERY sensitive subject without hurting his feelings. Any other suggestions?

Thanks
