I'm obsessed with sponges
What do you like about sponges?
They're good for washing and I like to use them as disgusting objects.
Using sponges as sexual objects has created an obsession that is weird and strange. Deal with your sexual preferences so that no one finds out about your odd obsession.
You can't tell me what to do. I love sponges.
It is fine for you to love sponges, but you should not let it become an obsession. It is a little weird to be obsessed that much with sponges.
