Just accept it as part of who you are. Fetishes are the spice of sexuality.

No you do not just accept this, masturbating on someone else’s clothing items is not okay and it might even be illegal. There’s nothing wrong with having sexual interests or fetishes but it’s inappropriate to involve other people without their consent, including their personal property.

Questions like this always make me assume the poster has some kind of kink where they like being shamed or told they’re bad or something in that vein.

My husband has what amounts to a fetish for my shoes, although he doesn’t go as far as to masturbate in them.
