(ΠSҒШ) Could you have sex with someone who is ugly?

Please don’t think I’m shallow, that was only a short version of the actual question which is:
Could you have sex with someone physically ugly, without having any real feelings for that person? I know that beauty isn’t everything and who they are on the inside is more important, but those are feelings. So pretend you don’t find their personality attractive, maybe they are a bad person, or just a complete stranger who is very unattractive, could you have sex with them with them, NSA?
