I have read a lot of posts here on reddit recently about how "the couples at the party were not as hot as we hoped" and "their pictures were not accurate enough" and "there was no good looking people there"...

That is all fine, and your preferences are valid and okay and fine.... if a bit shallow.

Personally, I prefer to get to know someone a little bit first. Even if they are not super hot, they might get that way with their attitude and personality.

This has happened to me (and my wife) like 3 or 4 times now... a couple we were not initially attracted to (but didn't repulse us obviously)....l turn out to be awesome folks and we share a deeper connection and then enjoy much more meaningful and fulfilling sex with them.

tldr; Anyways, my advice is to not focus so damn much on looks... give people a chance to win you over at a deeper level and you might get rewarded with the best sex in the LS yet!
