Tasks for sub men?

Hi ladies,

My partner is going away on a business trip for three weeks. As part of maintaining a sexual connection, we are discussing the possibility of requesting tasks of each other. I have thought of a few like asking him to masturbate using fresh chilli, using fresh ginger as a urethral plug and describe the experience to me, writing sexy stories etc however I would like more creative tasks that are either really kinky/ sexual or more romantic in nature. Any ideas??
