Have some fun
Think up fun ways to enjoy yourselves.
If the man has embraced male chastity and is locked away, he is available for teasing, stimulating with touch until he is desperate for release, then stopping, then starting again. You can tease a locked away male for hours and he will get more and more excited, until perhaps you let him have his release when he has begun to think he will be teased like this forever.
One option you might consider is to use handcuffs, one cuff to his left wrist, and the other to her right wrist. Stay like this for a few hours or even a whole day or a night.
You will be connected together and everything you do you will do together, whether helping each other eat or dress or wash or sleep or even walk you will be held together as one. Even basic activities such as going to the toilet will be done together as you cannot get free. This really brings closeness and intimate contact to a whole new level of closeness; it could be fun!
Write down one of your fantasies on a piece of paper. If both do this and then swap, and take time for reflection to think about whether they would like to do that sort of thing, then you can sit down, together, holding hands, and share your ideas on what has been proposed. If it seems a good idea after the pause for reflection, give it a go and see if you like it.
Play games with intimacy exercises, choose one to use in play and enjoy yourselves in what you do.
Learn together
There are skills in massage, tantric sex, or even in elements of housework, cooking or DIY which you can choose to learn together. As long as it is something you decide you both want to do, and it does not turn into a competition to see who can do it better than the other any learning together is an intimate experience.
You could consider doing a formal course together, or just going to talks and lectures. You could work on a project together which will benefit both of you. If your house is old and needs renovation why not learn together the skill to do the work.
It is not what you do together that matters but how you do it and why you are doing it.
