Suggest Remedy For Premature Ejaculation When On Cialis

I am 53 years old. Had a heart attack 7 years ago.I'm taking Metoprolol. I also take Lexapro. For the past 2 years I've been able to achieve an erection by taking Cialis. However, while I'm able to achieve multiple erections during intercourse, they usually don't last longer than about 2 or 3 minutes each. Is there anything I can do to achieve longer-lasting erections?
