Am I right to do this?

After being with my man for about 8 months I have decided to not have anymore until we get married but he has to let me play with his manhood to turn me on while I use a but he is not allowed to come or look at me so I make him lie under the blankets with his man bits poking out form the sheets while i have my fun. After i finish i send him home so its clean and there's no chance of us having again before we get married What do you think about this relationship and how long do you think its going to last?
