24F and 27M, has my boyfriend been red pilled?

I've been dating my current boyfriend for the past 5 months, we are both in our mid 20s for reference. Everything has been wonderful so far. We've exchanged I love you and are planning a future together. He leans more on the conservative side in terms of his ideology. He believes the man is the breadwinner and wants to work toward a future in which it would be optional for me to work if we had children. I am studying and planning on a high paying career - so this doesn't matter to me and I plan to maintain part time employment, irrespective of how things go. I would prefer a partner to be able to contribute to the relationship equally and don't mind if he earns a bit less. He frequently speaks to me about his distaste of so called 'sl*ts,' 'slags' and promiscuous women. To the point where he will stereotype certain personal style choices with the archetype. He is very anti-casual sex and has maintained voluntary celibacy in between relationships - though has been in relationships for most of his adult life. I have taken a preference to monogamous sex since dabbling in casual sex when I was younger 18-21, whilst not in a relationship, some might call this behavior promiscuous. I didn't have the best time with it and didn't feel it was for me long term. I haven't engaged in anything like that since then. He speaks often about topics such as men and women can't be friends, pair bonding, high value man (financial stability/wealth), high value woman (non-promiscuous/loyal/non flirtatious) and evolutionary biology... He is aware that I have had casual sex multiple times in a previous conversation we have had and was quite taken aback by it but has chosen to remain with me and hasn't shamed me for it in any way possible.

I honestly had no idea it was such a big deal to some people. I only knew that some people were religious and preferred to wait until marriage. I have never experienced regret over my past casual sexual encounters, my ex bf and I never spoke about this and I never thought about those experiences. I was raised in quite a liberal home and was told to enjoy sex and be safe and careful and have never met people who think differently. Now I just feel like a dirty sl*t with the way my boyfriend talks about it and it makes me super uncomfortable to hear him talk about women in that light. I have asked him to not use the word sl*t around me and has agreed to do so. I just can't shake the feeling that I get when he speaks about promiscuous women in that light and how he would feel if I ever detailed my sexual encounters to him. Some of my encounters were stupid and I found myself in questionable scenarios, ending in SA, thus I have left that in the past and tried to not think about it. I get flashbacks to those encounters every now and then and feel disgust since being with him.

I am not sure about how compatible we are long term if he feels like women who have engaged in promiscuity don't deserve to be treated with respect or spoken about respectfully. He also has this fear of infidelity and believes this is linked with promiscuity. In my previous relationship, I was loyal and never cheated, we ended on amicable terms due to a difference in priorities. I feel like detailing my past to my current boyfriend will just make him paranoid and mistrustful of me, if this is how he feels. I am hoping he will grow out of this thought process but am I naive in doing so? How can I challenge his thoughts without making it seem like its coming from a place of self-defense?
