I Let My Husband Do Things I Don't Like

When we first started dating and having sex, my husband and I had a great sex life. That was 14 years ago and he has constantly added things he wants to do to me, or have me do. It has been gradual granted and I have done all he wanted and still wants. I'm fine with our sex, it was great, I cum several times, and with others before him I didn't cum at all or only if I had room to rub myself during it. He knows how good it is for me but he needs more and more stimulation.
We started light then he wanted more.
Different positions, didn't mind at all
Nude beaches

Nude resorts, then resorts where sex was allowed anywhere

Sharing me for sex at these resorts (only me, he only did oral on other women, no sex)

Me and other women one on one for sex. I'm not bi at all and honestly don't like the taste of a womans pussy, but I did it for him and with incredible results.

Public flashing, parking lots, highway crossovers, in europe even walking a city block nude

Gangbangs, he's organized safe partners, first 5, then 8 now it's over 11 everytime creampied

He writes things on me, in permanent ink that doesn't come off for a week or more, nasty terrible things. My mother and my sister saw some writing and I was so embarrassed. That was "ass gangbanged by 5" on my butt, "Pinch" over one nipple and "twist' over the other. Then on my lower belly "cock sucking, gangbanged, cum guzzling , pass around whore. Free pussy" then an arrow point to my pussy. On my upper thigh, right next to my lips down there he marked "today's count" and put 9 hashmarks on me.

I told him we had to stop especially things that my family might see. Instead he said that he needed to find someone to have the kinky stuff with, and use me for love. "USE ME"
He doesn't go anywhere else, there is no need for him to. I'm his wife and I feel I should take care of my husband sexually, so I do.

I guess I am a cocksucking, gangbanged, cum guzzling, pass around whore!

But I do it so my husband doesn't cheat.
