I agree with Perna (as usual). A friend of mine went through a very similiar situation, prior to restarting the physical side of his relationship their therapist recommended intimate phyisical touching that did NOT lead to sex. Back rubs, foot rubs, etc. On a nights when they did not have to worry about work the next day, in their case her night was Friday and his Saturday. It was an exercise in intimacy without the fear/worry about what was to happen afterward. The only rules were that each partner had to be comfortable with the touching and they could NOT attempt to use the sessions to initiate sex.
