Using/sharing a dildo for strap on

Question for ladies - how comfortable would you be if someone used their own dildo on their strap on harness? Even if it’s cleaned and condom wrapped. Would/do you use your own (as long as it can attach), or prefer the owner of the strap on bring an unused dildo to use instead? We have picked up a couple inexpensive ones for that purpose and of course she gets to keep it.
