Unbound is number one on this list for a reason: It's the ultimate when it comes to sex toy subscription boxes. Each box is carefully curated with a combination high quality sex toys, body-friendly lubes and condoms, and/or sexy lingerie. You also pay significantly less than you would if you bought each item individually — and who doesn't like to save money?

Each box as a theme, ranging from slightly silly ones like the Harry Potter-themed Magic Wand Box to conceptual ones, like this quarter's Adentro box, which is inspired by the Surrealists. But no matter what the theme is, you're guaranteed something fun, sexy, and (too easy) outside the box.

You can sign up for one quarter for $65, two quarters for $115, or three quarters for $175. Unbound also offers individual boxes for sale and they have a whole shop where you can buy individual items, often at a steep discount.

Yeah, yeah, I know — porn is free everywhere on the internet. But a lot of that porn is created specifically for the male gaze and you never the circumstances under which it was created. If your partner is the type who likes their orgasms to be ethically-sourced, buy them a subscription to Erika Lust's XConfession series.

It'll set you back $34.95 for a month, $14.95 for a recurring monthly subscription, or $99.95 for a full year. Totally worth it — this stuff is hot.

If your partner is into lingerie — or you're into your partner in lingerie - check out SkivvieBox, which sends a customized box box of lingerie every month for $59. They carry high-end brands like Betsy Johnson and huit, so the value of the underwear in each box is between $100 and $150. Sounds like a good deal to me.

OK, so Pillow isn't exactly a subscription service, but it is something you can do with your partner long after February 14. Billing themselves as "Intimacy In A Box," Pillow offers five hours of 30 audio exercises that you can do over 30 days in order to build better intimacy with your partner. All of the exercises were created by therapists, coaches, and tantra teachers.

You can get all of that expert advice and a program that they say will "shake up" your relationship (in a good way!) for $49.

Sssh is a porn site that's created specifically for women. It's been around since 1999 and includes everything from original HD movies to original erotic TV programming to written erotica to sexy images. They also offer how-to guides and video tutorials, which really makes them a great one-stop sex shop.

A subscription to Sssh.com costs as little as $4.95 for two days or as much as $99.95 for a full year.

The Pleasure Pantry is a great option for people who want a little more control over their sex subscription box. The service starts by asking you a series of questions, stuff like your size, what you're into, and what gender you're attracted to. (I especially like that last option, a some services are pretty heteronormative.)

Monthly subscriptions cost $29 per month, a three-month trial subscription comes in at $34 per month, and the Deluxe monthly box costs $75.

The Fantasy Box is for heterosexual couples, with the first box containing elements of four different fantasies: control, "sensual," costume, and "playful." After the initial box, the next four will go more deeply into each category with toys and props to help you explore that fantasy.

The Fantasy Box comes at three levels: Essential for $39 per month, Classic for $59 per month, and Platinum for $159 per month.

Take that, haters! The love day will always win, in the end.
