You just have to exceed a relatively low threshold of attractiveness. As long as you're presentable and not a beast, looks are insignificant in comparison to other factors.
To really benefit from good looks to the point where you can rely on it as a crutch, you'd have to be in the top .5% percentile of men. Male model, Orlando Bloom type shit. The downside here is that tons of women disqualify themselves from entering a LTR with you out of insecurity, fear of being cheated on, and whatnot. But they do have a very easy time with flings -- plenty of girls want to be sexually validated by having a "gorgeous" guy sleep with them. Attractiveness beneath that level is only a slight advantage.
