I dress mainly as erotic pre session turn on; and since I don't want to dirty my clothes, I only wear them for 5-20 minutes.

If you are unable to machine wash them, you should consider hand washing. It's a bit more work but is easer on the fabric and can be done in private. That would allow you to wear them for longer periods of time for more enjoyment.

At first, when I Was married I would take my clothes over to laundry mat to wash them. Now that I have come out of the closet and no longer married, I wash them at home.
I have made the mistake of washing a few of clothes in the wrong cycle and ruined them. So I select the delicate cycle and do not put bleach. Washing women's clothes is a lot different than washing men's clothing.
