Feeling deeply ashamed of particular kink

Thank you everyone for all the amazing support and answers. Did not expect so many responses.

From what I gather this is quite common, and it being strange and weird is all in my head. For some reason sniffing someone's butt just is weird to me for some reason. But I have no intentions of stopping. So thanks 🙏 ❤️

So smelling someone I love has always been a big turn on for me. I think scent plays a huge part when falling in love with somebody. I think my girlfriend smells amazing, and especially so when she hasn't showered in a day or two.

I could lay with my face between her ass cheeks or eat her out for hours if she let me 😂 partly because I love giving her pleasure, but also because the smell is so good its intoxicating.

Once or twice we've had some fun and she has been on her peloton bike for half an hour in thermo thights to work up a real sweat and then I get to take them off and just bury my face in her ass.

She thinks I'm insane of course, and it's taken her a long time to trust that this is something I truly enjoy. And I think that she does too now that she can relax a bit, and take pleasure in my getting my desires fulfilled.

Obviously afterwards I always feel deeply ashamed and promise myself to not do it again, because, yeah it's a bit weird probably, but then I can't help myself and I just do it again and again.

Am I alone in having this fetish or have any of you women encountered this behavior before? If so, what was your experience and was it something you were ok with or even enjoyed?
