Would be interested to hear you elaborate on this…
Well, you know, these movies are flaunting skin in every scene. (Which is funny, because like you mentioned there are no sexual x-rated pay-offs). They're also shooting the women differently and devising tropes that show off the playmates without ridiculing them the way the men get dragged. They're these buff or strutting ideals of the powerful hetero-male, so much so that it helps with the whole vibe that this is an action movie farce.
I could have just said drag, but the tone seems to always mock the men in drag -- and it's never the women agents getting dressed like men. It's a "disguise" trope like, what, Some Like It Hot, but wrapped up in so much beefcake that either Sidaris is pandering or merely having a laugh about "how funny" it is to see men in drag. Considering the era, I felt like it was the latter, but didn't mind. Everyone's oiled up and hot, anyway.
Will probably watch more of his films in the coming year. They went well with friends and drinks.
FAB Press is republishing the long-OOP book 'The Ghastly One: The 42nd Street Netherworld of Director Andy Milligan', with newly added material.
Pre-orders will include a one-off printing of a 300-page book of previously unpublished Andy Milligan scripts.

There's an interesting interview with the author, Jimmy McDonough, up at Diabolique Magazine
This is so exciting. Hoping to submit to the Milligan contest on ByNWR.
