We have been together 3 years. I am always asking for sex. I get it maybe 1-2 times a month. If I ask after work, he waits until we are in bed, very predictable. He then will start a bit of foreplay. Then he seems to wait tooo long before continuing. I need momentum to remain and get further aroused. He acts lost, I tell him what I need. He then will do it one time, then nothing. He then seems to forget everything I have praised him about and won't do them on subsequent sexual encounters. I tell me I need to be mentally/emotionally aroused....I tell him EXACTLY what I need he to say and do.......I even try to walk around naked.......He won't try to have sex with me then either. He's always too tired, hot, hungry...etc., to have sex. Every other man I have been with, all I had to do was ask for sex, grab his dick or walk by him naked to have sex!! I am lost.
