Real sexologist? People actually listen to what you say and even pay you for that LOL
This also interests me in some degree as I like to know how things work. and I would like to discuss my theories with someone as well so wee how accurate I got everything and what needs some adjustment.

I think impregnation (if this is "impregnation" and not "pregnancy" ) is a pretty destructive thing. I am not much interested in that myself but from what I read on manga and other fantasies you can talk about your fertility as you forgot to take a pill, you are on your dangerous day, you will definitely get pregnant if he cums inside.
Also you can talk complete nonsense as how you can get pregnant from anal oral/sex or any body fluid getting anywhere on you. describe how his sperm is traveling in your belly into your ovaries

Talking about how much you want his cum and babies do not seem to be that much related to this fetish since you have to show your fertility and not your desire to have babies
I think it may be even better to do opposite as complain about how dangerous it is and how easily you can get pregnant and then you will have his baby. In this situation, you may ask him "to take responsibility and be a father". Or you can alternate your atitude from being scared to willing. as you complain at first and then say how much you want his baby. Maybe you can even be more dominant and tell that now that he made you pregnant he all belongs to you.

Considering that "consensual rape" thing I think it is logically impossible and quite ridiculous. Sure you can play some fantasy scenario with your boyfriend pretending to be a rapist and you pretending to be scared or something but it is all obviously fake and you both will know that.
While if you will get assaulted without knowing that it is fake it will be real rape and I wonder how you would react to the real thing if you will get raped by some stranger.

Logically valid "consensual rape" is actually known as tsundere personality. just like in one hentai movie one character said:
"if you force me to have sex I will object and fight back but I will not get angry"
