[Advice Needed] I'm SURE there HAS to be a way to monetize this

So here's the deal.....

One of my adult tube sites has, on its own and without any sort of CTA to solicit them, grown a list of over 2k email-verified members in the last 3 months... The only way for them to have submitted this info would, up this point, have been to literally go to "Submit Your Clips" (a menu option which I haven't done anything to draw particular attention to)...The "accidental" aspect of this scenario is a lot of what has me caught off guard lol...

Anyway, this site happens to be A Micro-Niche Tube Site Specifically catering to the Gay PNP (Party and Play/Recreational drug enthusiast) community - my users tend to be highly engaged and enthusiastic - good buying signs...The GEO and Demographics are also on target, roughly 90% US, next top GEOS are CA, UK, AU, DE, NL and Sweden....The Overwhelming majority of visitors seem to be using Apple products (mostly mobile traffic from iPhone 7 and newer and iPad) - Desktop traffic is more mac than windows, and the majority of Android visitors (which more than windows desktop but dwarfed by iPhones) are Samsung Galaxy 7 or 8, something like 3-5% of traffic comes from devices other than the ones I just mentioned - which leads me to believe that these are not "derelict" partiers, these are partiers with $$$$ Disposable income....

Quantcast data reinforces that theory to an extent, showing me that the majority of my visitors are white/latino males 30-45 with a Bachelor's Degree or higher, and who earn more than 50k/year.....

Now My first reaction in coming into this realization was "GREAT!!!!! Lets put up an easier to find email submit form and see if we can grow it even faster and ...." BAM - that's where the problem lies - What the F To sell them???

I'm already an affiliate with Crakrevenue, Peerfly, and some other networks as well.....I was certain I would come across an offer that would fit the demographic that allows email promotion - but to my complete shock, I couldn't find any... .NOT ONE.....

Crakrevenue DOES have some that allow email promotion and that target US - but every single one of those offers happens to be geared towards HETEROsexuals - none of them catering to the Gay niche...and the offers they currently have (at least every one I saw, and I'm pretty sure I went through each and every one of them) that are targeted towards Gay men and US GEO all forbid promotion via email.....

PeerFly's few adult offers forbid email promotion as well...and the other ad and affiliate networks I work with currently came up dry as well... I did a thorough search on Offervault and Odigger as well - nada....

Also feverishly searched Google, BHW, wJunction, CPAElites, and others for adult email ad networks, adult email affiliate programs, adult email CPA, Selling Email lists, Buying Email lists.... NADA from any more recent than 2013ish and nothing entirely relevant, much to my shock...

Then again, I started this site with the expectation of it just bringing in a few dollars a month in ad revenue from CPM/CPC and maybe a few CPA sales/opt-ins here and there, so this is really a "bonus predicament" if you will, but nevertheless, I'm totally stumped...

So I'm wondering:

SHOULD I throw up that more obvious email submit in order to attempt to collect as many as possible NOW or wait until I know what the F** I'm going to do with those emails?

Does anyone know of any networks or indie programs that fit this audience demographic that would allow email promotion? or do any CPM/CPC Email Newsletter ad networks exist anymore?

Should I Rent or Sell my email list? is that a thing anymore?

I can't help but think that this is a goldmine I'm sitting on for either: Gay dating/hookup, Adult Toys/Costumes/etc, Sexual Health/Stamina/Testosterone/boner pills, men's anti-aging, and specialty fetish niche paysites (and maybe cam sites, but probably less so than the aforementioned)...BUT I JUST CAN'T FIND AN OFFER THAT WILL ALLOW ME TO PROMOTE VIA EMAIL!!!!

Anyway, LMK What you guys think and more importantly - if you know of any offers and/or networks that I don't know about that would allow this type of promotional method that would do well with this audience

Thanks!
