It's a rather far jump to go from handshake to sexual favours in my opinion, but if you feel that way then of course you can just choose to not shake people's hands. Nobody forcing you to after all!
No pressure.
Just an FYI: I'm a woman. In my experience, a lot of men looking for excuses to touch me, such as shake my hand, are really angling to get next to me sexually.
Maybe that's not a big issue in your life. It unfortunately is in mine.
Edit: just to be crystal clear, my reason for not shaking hands is germ control, as stated elsewhere.
But yes, in general if a society places enough value on a social norm to decide whether or not to do business with a certain person it is possible that certain people will be alienated based on their willingness to participate in such a social norm.
And, to address your edit: I am fully aware that we are currently in a pandemic and I am not saying that we should go around and start getting overly close to one another for no reason.
As the original content all the way up this chain I was mostly referring to a time post COVID, assuming that such an outset is realistic. If not then hand shaking will be the least pressing problem regardless.
I don't really think the pandemic will end without social norms changing. Handshakes are a social norm that spreads germs. I think we would do well to move to something else. In many cultures they bow.
So my belief is that we only get to post pandemic by doing away with things like handshakes. That's my opinion and I can't back it up with studies or anything, but your mental models and mine just don't mesh well in that regard.
You have a good day. I think you and I are likely speaking somewhat past each other and I'm not interested in engaging further in what is likely pointless miscommunication.
Yes, sure, people should make reasonable accommodations to help deal with your extreme minority situation.
But it is a sure for you to demand that everyone else change their entire lives, and perfectly reasonable preferences, to satisfy only you.
