When you have a draw full off baby wipes and another full off sex toys, handcuffs, whips etc.
When you go shopping for real life clothes and end up buying work clothes/underwear/shoes aswell or instead.
When you have no shame in buying condoms, lubes etc from supermarkets, chemists etc, in bulk because there is a special offer on and get baffled when you get funny looks from the woman at the till.
When you always check how easy an item of clothing is to take off before you buy it.
