This is a fairly serious question albeit difficult to articulate.
I'm not going to bore you with some really super detailed scenario. Let's just sufficient to say that though some means you were attacked violently and off guard by a member of your sexual preference. Let's also say that there was an initiation of a sexual assault on you in which from the initial physical attack and to some point in the sexual assault you were obstructed from any visualization of your attacker. If at some point in the middle or towards the end of the sexual assault you were able to get a good look at the attacker, do you believe their appearance level would effect your view of the situation.
To be slightly less seriously, let's say you yourself are middle of the road "5 or 6" on the number scale and your attacker is a "9 or 10" by your own measure. Do you believe this would change things for you?
