Dating after Easter seems clearer to me. If a 'special' day crops up then Steve can have No expectation of sexual contact. Sue may engage in a bit of mutual masturbation or maybe finish a hand job but might not even go that far. Perversely, special days would carry a higher expectation, more pressure for her to deliver, so she might not, to stay in her role. On the other hand, some other dates there would be zero expectation and Sue may just be feeling horny for Steve. That to me is when the condoms may come out in future. Just not very often. Enough to keep the memory alive though. Just my guess...
