No, creepiness exists in your mind only. Believe it or not, we valued the fact that those women were there and we tried to help them out in whatever way we could. My field of study back then (guidance systems, weapons design) is even more male dominated than CS. All male peer groups are not a fun thing to be in.
To preclude the question, yes those girls did get asked for a date every now and then. If that’s wrong, I don’t want to be right.
