"I like to include people when I am having fun ..."
Can relate to that.
If you passionately wish to share all with your lovers (including each waking and sleeping moment), then exercise with you they must!
But you'll have to excuse them for a moment if they step into the ladies' room or the dressing room at a department store.
Fitness is good for everyone so I have no problem with you wanting a lover to join in the pursuit of it. In the meantime, we'll just share some good old times from our distantly-situated computer chairs.
