Hey there,
Some friends of mine are setting up a global sex positive directory called Soul Kittens and they're currently running a fundraising campaign, with perks including advertisement. It looks like a really exciting project and something that I hope a lot of people will want to back. If it doesn't make the target amount all donations will be refunded, so I really hope it gets there!
There's lots more info on the fundraising page here: https://www.indiegogo.com/projects/soulkittens-a-portal-for-all-things-sex-positive
