I'm not sure if this is exactly the same thing as what you're going through, but I feel the same way.
I appreciate that my husband understands my feelings about this so called "fetish". For me it's not sexual at all but entirely playful, however that being said, it doesn't make it any easier for me to be comfortable around him when it comes to it.
Alot of people would consider it not being comfortable in your own skin (in my case) and they may very well be right. I can't begin to tell you how akward it is when he starts to talk about it, or starts talking about how I "like it". My immediate reaction is to change the topic to anything else...
Yes, I like it, occassionally, but it's not something that I like to dwell on, or even have it come up in discussion.
You may also be feeling embaressed because you KNOW he knows you like it.. That might sound weird, but I know for me it changed the dynamic of how I looked at this entire fetish... My feeling's havn't changed about it, I still only like it playfully, but I just don't have the care free attitude that I had before I told him... I'm always self-conscious now
