That's a sign that he likes you. He wants you to see his manly side and make you feel more secure. It may also mean that you are more beautiful. Show it to your friends. This is a man's vanity. I personally suggest that you should be satisfied. If he can't stand it, he can be advised to change his environment. A better gym. Personal suggestions, I hope to adopt. Thank you. I wish you both a long and happy life.
