You could try viagra but I will tell ya what, that stuff sucks. The side effects are terrible. Have you ever tried a sexual enhancer? I was in your situation, like I said, viagra was tried but it wasn't for me considering the side effects overwhelm the pleasures of it. I found this natural herbal enhancer and figured what the heck, if it's natural it must be great and plus it said no side effects. I tried it and after about two days of taking it I was just horny like a mad man. All the time, I have erections that want to stand straight up and the orgasms are to die for. The stuff was called vigrx plus and I saved on it at the time at http://hughs-reviews.com, You should check it out. I love the fact it's made from a researched blend of herbs that seem to do the trick for me atleast.
Good luck and I hope this helps.
