This type of fetish is more popular in amateur porn, if you are fine with that, then there is a reasonable number of videos to explore on xhamster, for example. You'd get something like this:

TIM did this since "dangerous/toxic sex" is part of their whole brand, but in interviews, actors said that even then they were selective with cum doners (though this was about those videos where they inject 50 or more cumshots in the ass with a big syringe or turkey filler). Amateur porn is not bound by such regulations, so for private shows it is relatively easy to do.
The point here is that if you're looking for studio-quality scenes, you may need to sacrifice the amount of frozen cum, which brings me to the second question (which, I apologize, I should have asked together with my first one): is the amount of cum important to you? Is it the large dildo-shaped amount of frozen cum that you look for, or any amount of cum is good, so long as it is frozen?
Id the latter is the case, HungYoungBrit did a scene "Cheeky Essex lad gets frozen spunk reamed up his arse". The name says it all, really, but be advised that frozen cum there amounts to one ejaculation only, and that whole part is relatively brief. You can see the preview here:

See what you think about these.
Annion you're simply fantastic! Thank you so much for the detailed (and competent) reply.
Sorry I miss the full meaning of your question before.
To be honest I don't care about the amount of cum used. The size of the "dildo" isn't important.
I saw the movie with the turkey filler and also the one with the jar labeled "dog cum" (in that case cum was partially melted) and they didn't excite me at all so I can tell that the amount used is not important to me.
I simply like the idea of freeze and use cum, whatever the use.
I'll watch those clips later this evening and follow your hint of looking for amateur material.
Thanks again!
