First off, I think you're a very polite guy and that's an attractive quality in any man. You need to stop believing what you hear. It's not true. You will say that every night before you turn in. Not everyone can be a raving beauty, speaking from personal experience, and I had to overcome a lot.Cumberbund is downright fugly.
As a guy whose been told many, many times in his life that he's "fugly" - and much worse - even by total strangers passing in the street, I can only reiterate that I'd swap looks with Benedict any day.
As for Star Trek, apart from the instructors you see from afar, do they have ugly female characters? Are Alice Eve, Elly Kaye, Nazneen Contractor and Kraisit Agnew ugly? BC is supposed to played a genetically enhanced character. It would be more believable if he were a Klingon augment. They didn't pick and choose who to deliver the virus too. Human augments from the late 20th century were chosen and someone who had flaws would have met a very short end.
I guess what I'm saying is, if the guys get their gorgeous, leggy gals, why can't we women have our gorgeous, chesty hunks.
