erectile dysfunction
"Having struggled for about 12 months to maintain  an erection my Dr recommended Viagra. Wow minimal side effects occasional headache but that's because blood is rushing away from my head. The erections are like when I was 20. Takes effect after about 30 minutes and my wife only needs to look at me and I get hard not lasting any longer but the beauty is I can get hard 4 or 5 times over 3 to 5 hours and again in the morning. We are late 40's but we feel like 20 year Olds."
