17 Things That Changed Our Sex Lives In 2015

::praise hands emoji::

When it comes to sex, variety is a ~wonderful~ thing.

And in 2015, there was a lot of that going around — from innovations in sex toys and medicine to a ton of sex-positive people, books, and podcasts. Here are a few of the many great things from 2015 that made some people's sex lives better (or at least more informed).

1. This hands-free vibrator that sits between your labia during sex.

After fundraising in 2014, Eva went on the market this year. You can buy it for $105 here.

2. First Person, the YouTube series from PBS about gender identity and sexuality.

There are 20 episodes so far, covering topics like asexuality, bisexuality erasure, gender binaries, and so, so much more. You can find all of the episodes here.

3. Marnie's analingus scene on Girls.

4. A suction-based clitoris stimulator.

Despite its tacky casing, the Womanizer gets good reviews. Instead of using vibrations, it lightly "sucks" on your clitoris. You can get it for $189 here.

5. Elvie, a Kegel trainer for women that connects to your phone.

6. kGoal boost, a Kegel trainer for dudes.

7. Alice Dreger's badass live tweeting of her son's abstinence-only sex ed class.

8. When Abbi decided to try pegging on Broad City.

9. Rebecca Traister's New York Magazine article on how consensual sex can still be bad sex.

10. The BuzzFeed Health Sex Q&A series.

At the risk of sounding self-promotional: this series of clear, expert-informed answers to reader-submitted questions can teach you more about sex and sexuality than any sex ed class will. You can read them all here, but here are some highlights:

Why Can't I Orgasm?

How Safe Are Rim Jobs, Actually?

Does Bottoming Have to Hurt?

Can I Pee Inside My Wife?

Why Isn't My Boyfriend Orgasming During Sex?

11. Women on Sex, a YouTube series that features African women talking frankly about sex and the culture around sex.

16. The book The Women on My Couch by Brandy Engler, Ph.D.

Engler is a sex and relationship therapist working in New York and L.A. This is her second book (her first was The Men on My Couch), and it tells the stories of women and their struggles with sex and relationships. BuzzFeed Life talked to her about some of the most common reasons people see her, which you can read here.

17. And, uh, the Ovipositor.
