Eh?? I thought the OP once said he was a conservative who just wanted a modest traditional girl with good values or something like that? LOL!
Well, here's my own answer to the questions:
Assuming this "absolute sexual attraction potency" lasted permanently (not just long enough to get women into the sack)... Ironically I might actually swing a bit in the direction of less womanizing, rather than more (like most of you seem to prefer), even if not in the completely monogamist sense of
@Outcast9428 and
@MrMan.
The kicker is that in exclusive relationships, the mutual attraction normally doesn't stay as strong as the cyclone of love chemicals and hormones subsides (even if attraction sometimes is still there after years, but in the studies I've read it tends to deflate significantly anywhere between 6 months to a year into the relationship, which is one of many reasons why most relationships and marriages end).
I'd have to put some thought into whether to use this absolute potency to get comparatively monogamous with the hottest woman of my choice, or go more for 3 or so wives....
Probably the latter, because it'd be good to build a large clan-like extended family

FWB is mostly what I already do, so ironically unlike
@Lucas88, I'd actually do less FWB and "play the field" less.
I'd definitely still go abroad, to the exact same countries I'm interested in now.
Would I be the same person? Most definitely!
As for making use of this absolute attraction potency, I'd probably go on with plans to practice as a hypnotist (which already tends to be of interest to women even with less than "absolute" sexual attraction potency).
But I'd definitely more aggressively target wealthy women as clients (not to be predatory or snobby in desiring to hang out with such people, since I'd rather hang out with non-wealthy down-to-earth people personally, but so I could charge the highest possible rates in the interest of accumulating the maximum amount of $$$ with the least amount of time and work).
I'm probably actually am going to do something like that in the next few years anyway, but knowing I had absolute potency and personal magnetism over any woman would embolden me and make the marketing and client prospecting side of the business much faster and easier.
Then after I was rolling in $$$ and had my capital steadily growing from investing it various places, I'd probably become some better-looking version of a Rasputin-like character, but instead of seducing or mesmerizing "elite" powerful and wealthy women, I'd go about convincing them of the evils of homosexuality, transgenderism and globohomo, and persuading them to direct their influence and wealth toward helping the Ugandans and Africans and others pass their anti-homosexuality legislation and defend their nations.
Well, there's what I'd do.
As for the women I'd choose, I still don't give lame numeric scores to women, but here's the types I'd otherwise consider "tens" according to my own standards (reposted image links from the "Curviest women in the world" thread, LOL):
