When some asks what’s your spec in a man,? can you say “just look good and you’re highly attracted to intelligent men”

Yes, you can certainly express your preferences that way! Saying "just look good" suggests that physical attraction is important to you, while stating that you're "highly attracted to intelligent men" indicates that you value intellect as well. However, you might consider expanding on your answer a bit to convey a more complete picture of what you find attractive. For example, you could say something like, "I appreciate someone who looks good, but I also find intelligence and a great sense of humor very attractive." This provides a more nuanced view of your preferences.
