Kinda odd

So my husband has recently wanted to start using condoms. It’s odd because he hated them but lately he has switched it up. We have a old stash from when we were dating and during our process of moving he keeps saying he wants us to use the condoms.

Edit: I’m on birth control stash is about 2-3 years old

I have asked him; he says because he doesn’t feel “clean”

He does have a really bad lying problem
