My fiances penis only gets semi hard.. It was completely hard once out of all the times we made love.. And he does not have the normal sexual desire that a man usually has.. We dated once before about 10 years ago and had sex everyday and it was great, but he did have a problem with alcoholism back then.. Now he seems lees interested and says thats all I think about.. When we first got back together this time around we had sex more passionately, but now it seems like its not really there.. I dont know whats wrong, he says he is just older than he used to be..
