A man who is intimidated by you for your accomplishments is someone you shouldn’t waste your time with.
I’m (ahem) tall, and accomplished. And I would date you in a heartbeat. I am, though, happily married (to a very accomplished woman who I love with all my heart). But there are others like me out there , I believe.
In any case, most men on dating sites are there because ‘real life’ offers them few options. That should tell you something right there, in any case.
