My fiancé and I are very affectionate, but I have a high libido (wanting release once a day) and he has a very low libido (wanting release once a month).
I remember coming across a picture of someone's OC holding a black and blue marbled Fenrir and saying "It's beautiful..."
And ever since I kinda lurked on Bad Dragon for months before building the courage to ask him about it. I sat my partner down and asked him if he would be opposed to me buying a sex toy, and I showed him Crackers.
At first he was a little upset, thinking he was not satisfying me, but I reassured him that this was meant to enhance our relationship and not "replace it." That silicone was no substitute for a person, and he could use it on me for nights when he wasn't into it. (Our families/school/town discourages sex and fornication, so I don't blame him for being anxious.)
And maybe I bribed him with a Sugar Star to help the process along
He's very supportive now, and he owns two penetrables with a third on the way, and even asks if there are toys he can get to use on me-- it's a win-win and I could not ask for a better partner.
