I’ve done both with Fido (my pump) in intimate situations.
If I go off the lead, all that really concerns is that overenthusiatic grabbing doesn’t catch the cannula. I suppose I should finesse my basals before & after, but the exertion usually means I’m reaching for the Lucozade!
I I stay attached however, remaining unentangled & ensuring Fido doesn’t try & join in the intimacy can be issues. He once buzzed in very close proximity to a very sensitive & recently sensitised place. Suppose he wanted intimacy too. Unfortunately, the lady was shocked rather than amused.
At the end of the day, it is like all things diabolic. It requires a little effort to integrate it into your life & usually it eventually provides an amusing tale.
