Bf described girls as ‘hot as hell’, is now going on a trip to the red district in Amsterdam with a friend, feeling concerned

Hi all. So I’ve been dating a guy for a little under 2 months. I like him and he likes me. He’s a good looking doctor.

He has had many ex’s and casual things in the past but says he wants to find a girl to marry as he is getting older now. I also want a long term thing.

Yesterday we both went to a club. It was a nice place and we had a good time. Today he told me that the girls there were ‘hit as hell’. We’ve spoken about other beautiful women in the past which I actually enjoyed, but this phrase kinda bothered me. Later, I told him it bothered me and he told me he said it on purpose to see if I’d be jealous.

He is also going on a trip with a friend to Amsterdam and will be visiting the red district. He said his friend wants to pay for a prostitute there and wants my boyfriend to come to that particular area with him as he has some social anxiety going alone. My boyfriend assured me that he will not see a prostitute, that he feels bad if his friend goes by himself so will come with him but will wait on the streets. He said he’d never see a prostitute, that he has higher standards and would be too concerned about sexual diseases.

Is this stuff a red flag?
