Keep the body in the best shape possible. Keep your mind alert and well. Maintain your habits of worship and do things for other people. When my wife's mother was 92 years old she opened a thrift shop to sell things to help the old folks. Helping people is a key, believe it or not, to a fulfilling sex life in the elderly.
Sexual preference is as variable as culture and food habits.
One man's poison is another man's food. The bottom-line suggestion is to please each other. If you are not pleasing each other, then talk about sex, read and study it, take some counsel from a licensed sex therapist, adapt and change a little until both partners are pleased. Sometimes a partner complains about the other person as an excuse to find another contact. If you would like to advertise on Seniors-Site please contact us.
