Some context.. My partner f37 and I m38 have been together since just after high school. I was her first and only. I have no interest in anyone else but her however I would love for her to have more.

I have mentioned cuckolding a few times over the years and her response has always been a no. I have brought it up again just recently but she hasn't really acknowledged it.

In short I've tried to introduce toys and some porn and a few other ideas but she always says she prefers me then a toy or isnt really into anything.

I get that it's not for everyone and I definitely don't want to make her do something she doesn't want to. She's the only one the could forfill my fantasies due to my feelings for her.

Should I just give up and mark it down as a lost cause and continue with vanilla everything? Is there anything worth trying?
