My rav was matir me to shave for early dates during sefira and the three weeks. I’m not posting his name.
The point is though, why are you sitting and bickering on this thread? If you want to know if poskim are matir, call a few. Most of the American poskim speak English and should be able to communicate with you (if you speak English).
While you’re on the phone with them, ask them if girls are allowed to congregate in the street, why beer doesn’t need a hechsher, if you should get lap-band surgery, what bracha to make on pizza, if fish are muttar, if the internet is muttar, and for a good question to post on my yoreh deah choshen mishpat thread.
