Have a look at Thane from Mass Effect, he seemed pretty popular with female gamers.
I think combining the "loving caring & cute" attitude along with the "dangerous and mysterious" thing can lead to success. You'd probably wonna go ahead and make him pretty "manly" then: pretty well trained but not over the top.
You could also go the bishounen route, aka: make a boy who is soft and fragile and a bit womanlike and "cute" in appearance. But still make him dangerous and mysterious. No body hair there, clothes can be a bit more daring.
Thane was made for that goal of attracting women, but I think Garrus is the better example, I.E. 4:17-ish:

They even tried to keep Garrus "handsome." His given power was armor piercing ammo, too, and I like that.
Honestly, I like Zaeed more than Thane. The scar, the accented, throaty voice, the interesting stories, the mentality, etc.
Thane was just a little too blatant, IMO. Yeah, they explained why he dresses like a Klingon woman, but he just came off as a bit too rebound/clingy. I dunno, he seemed really eager to latch on to Shepard, and hell if I know why, really.
Loki of the Avengers/Thor movies works, apparently.

I think personality has a good bit to do with it, though it seems like it's just physical being talked about, here.
I'm pretty weird, I guess, but for me, Patrick Stewart, Alton Brown, and Terry Crews look physically nice, which are really some far ends of the spectrum away from one another, but I guess the whole personality thing kicks in with them, too.
