My husband is impotent due to his MSA however he has become more interested in sex than ever before. He cannot control his body so it is like being in a wrestling match and I have frequently been hurt. He will approach me anywhere in the house at any time provided he can walk the few steps to get to me and he won't be put off by refusal. He wants to "play" with my body for an hour or more each time and I really, really find it all very off putting given that he is incontinent often needs to change. Does any one else have this problem? What do I do?
