Hey Byron4u you should definitely claim that. Leone55 makes a good point too.
Soon after meeting the wife I share she reluctantly accepted a finger up her arse. Addressing the issue she told me she'd previously done anal with a lot of men. She stopped anal when she re-married and bred. Her husband who'd had anal regularly before marrying and breeding her. He also got denied but he's always trying.
I started fingering her arse at every opportunity. She squealed a bit at first then she would relax to accept it. Don't forget that in the past she was fucked up the arse by anyone who wanted it including hubby2 before they married. I bought one of those U shaped toys that goes in the pussy and normally the other end presses on the clit. I had her wearing it in her pussy and arse. Just a thin strip of purple silicone joining her holes. Anal play gets her off too.
A while later at the end of a day and night of play we were laying in bed in a spooning position. Me behind leisurely fucking her pussy. from behind in a spooning position. Ever hopeful I pressed my cock on her back door. She'd already cum a few times and she just guided me in. Her back door has been open ever since. She takes replica cocks too. Although hubby2 fucks her when he wants there's no arsehole for him.
Apparently hubby's dick is bigger than mine. Maybe that's your wife's concern.
