My husband and his female colleagues

I love my husband have no questions about his loyalty etc, we have a great life and children. But, it’s like every women at his work seems to develop a crush on him or has some hidden feelings for him. I find him super attractive and expect other women do too! But how do I deal with this? We were recently out and a female colleague of his came up to him, while he was standing with me, pulled him by the arm, and was talking to him very close to face, he turned around to introduce me to her and she looked at me then walked away. He was really apologetic for her that - not like it was his fault. But he didn’t feel he could say anything to her, she spent the rest of the evening steering at me with resting bitch face and then was joined in by another colleague. Now, I’m no super model, I’m married to him, with a child and house, I’m just not sure how to handle this? Or if it happens again. I felt so uncomfortable and it makes me feel for my husband going to work with these women who think he’s there’s. Because, another time a friend of ours who he hadn’t seen in ages, came up to him and gave him a kiss and a hug ( greeting like), because they haven’t seen each other, and one of those same girls turned around and said to the group “who the F is that”. I’ve just not been in this situation, he works predominantly with females, and loves his job asides from this. Thanks for any advice ladies / men lurkers :)
