Two people with very different sex drives can be a big problem in a relationship. As time goes on the hurt feeling can multiply. Resentments can build . Little things can become big issues and hurt the relationship. Are the two of you able to talk about it in a loving way? He maybe under a lot of stress at work. Is he on any Medication? He may have a physical problem. Has he seen a Dr? Maybe some of his needs are not being met? Do you wait for him to make the first move? Are you willing to be the one to make the first move? The best thing to do is tell him what your needs are. Ask him what he needs and wants out of the sexual part of your relationship. Maybe he will open up. It is said the sexiest organ in the body is the Brain. Good communication is the only way to really stimulate the That sexy organ. Being open an honest with each other is the only way you will be able to get this worked out. Do this in a loving caring way without pressure.
