Wanting opinions...

So me and my husband like anal a lot. Havent dont anything in awhile as i had a baby in October. Wanna get back into it but need some prep. We have 2 older kids (2, 4). I am what others think about if it'sts ok to secertly amd discreetly wear a plug around the house to get readyfor night? Most of me thinks it should be fine as the kids wont ever know and it isn't sexual at that time but the mom part wonders if it is just not ok at all for whatever reason.
