Here are some general links about human sexuality which you may find useful.
This is by no means an exhaustive list, of course.
https://www.open-love.org/ – Organization about nonmonogamous relationships.
https://askingforwhatyouwant.com/8-ways-to-hear-a-no-gracefully/ – It’s important to be able to hear and say no in all areas of life, but especially with regards to consent!
https://sexpositivefamilies.com/ – Mature discussions about sex naturally also involve families and children.
https://www.auntievice.com/ – I’ve attended one of her workshops before, she’s an older queer person with lots of experience.
https://www.aasect.org/referral-directory – Though I owe my therapist a lot, I’ve run into issues with her because she doesn’t understand alternative forms of sexuality very well.
Some training and certification in this area is definitely helpful.
The /sex subreddit is actually a pretty decent place, which plenty of its own links and resources. As with all online forums, exercise discernment and don’t feel the trolls.
https://iiseglobal.org/ – I had the honor of speaking at one of their conferences in 2024. They are doing their best to make the world a sex positive place!
https://www.youtube.com/live/djNw4R1KM1k – I was on a podcast speaking about human sexuality which you might find interesting – or not!
I have far too many resources to recommend, but I’ll just go over some that I find might be useful.
Brene Brown writes about boundaries quite skillfully.
Marshall Rosenberg’s NVC (Non Violent Communication) is a potential communication resource.
David Richo’s How to be an Adult in Relationships is a good book for well, adult relationships.
Gender Queer : A Memoir. An autobiographical comic that is not specifically about relationships, but explores gender and definitions.
Oh Joy Sex Toy! Is a sex-positive comic that touches on some of the points we have covered today.
Girl Sex 101 is obviously lesbian-centric, but has good information on relationships and boundaries.
The website Mojoupgrade is a good resource for couples negotiating aspects of their sex life. Communication is sexy!
An oldie but goodie – I would be remiss if I did not at least include a mention of the Ethical Slut. It’s a classic for reason, being the seminal text on polyamorous relationships. It’s worth reading if you even have the slightest interest in it – maybe you’re not sure if you are poly, or you want to understand poly people better.
Jessica Fern’s work (Polysecure and Polywise) is recommended for people learning how to construct functional polyamorous relationships.
Her work would be a logical step forwards from the Ethical Slut, if you still had questions or just wanted to know more.
