Following the trend of sites like Birchbox that send you beauty swag each month, subscription-based sex kits are now showing up in mailboxes across the country. Déjàmor.com offers monthly gifts, each one containing two boxes filled with sultry props and instructions: one "for his eyes only" and one "for her eyes only" (starting at $34.95 for one month). Bedroom Chemist sends out a "Chemist’s Kit" to subscribers every six weeks with sexy products like massage candles or a balm designed to spice up foreplay (starting at $49.99 for one month). And if you join Boink Box, you can pick between the Make Out Box for $25/mo (includes lube and small sexy items), the $50 Monthly Box (lube, sex toys and other fun items) or the quarterly Luxury box for $85 (luxury toys, lube and surprises). Bonus: They all come in unmarked boxes, so you don't have to worry about any awkward run-ins at your mailbox.
