Is this normal?

Not good that sort of behaviour is it? I would be most offended

Ask him how he would feel if you continually eye up other men.

Some men are just like that and incurable. Others like my other half wouldn't notice if other women strolled about naked. They are what they are and we put up with them....or not. I wonder if your husband would continue with this if you stopped noticing it and remarking on it.

I would be acutely embarrassed and offended by his behaviour and find it unacceptable. Don’t know how anyone would find it didn’t bother them. It seems as if you have just put up with it so he is unlikely to ever change. I think most would not be interested in a man in his 60’s though, probably feel sorry for his partner.

I'm wondering if you've been together for a long time and he has always been like this of if it started later on in your relationship. It feels as if it's something that you have been unhappy about for a while.
Some men do become slightly more disinhibited or inappropriate as they get older which can be linked to dementia but I'm not sure this is what is happening here. I don't think women in their twenties usually have interest in men in their sixties though. Look after yourself and don't let this make you feel bad.

No it’s not normal for a married or committed man but some men are full on flirts it’s not comfortable for you but if he’s always done it that is the man you hooked up with and he won’t change now, that’s his norm always on the lookout for a bit of flirting, a bit of flattery, a bit of attention, as you say it’s more noticeable now as you had less mixing in lockdown but that’s it I m afraid it’s as normal to him as breathing
Has he ever been unfaithful or are you suspicious he may
have ?
It’s vey unflattering and uncomfortable for you but no it’s not the norm and no he won’t change

but presumably he has been doing this all the time, and you were happy to marry him.
it's going to be difficult to change now. unless he wants to, and makes a great effort. which seems unlikely.
sorry. but i think anyone would hate that. nor is it universal.

*generally
