No, smart guys do not only like smart girls. Just like any other group of individuals, people's preferences and attractions are diverse and multifaceted. Intelligence is just one characteristic that some individuals may find attractive, but it is not the sole determining factor in romantic connections.
Attraction is influenced by a wide range of factors, including personality, shared interests, values, sense of humor, physical appearance, emotional compatibility, and more. Different people are drawn to different qualities, and intelligence may or may not be a priority for everyone.
Some smart guys may specifically seek out partners who share their intellectual curiosity and passion for learning. They may appreciate the stimulation of engaging in deep conversations and discussing complex ideas with someone who is similarly intellectually inclined. However, this doesn't mean that they exclusively seek out smart girls or dismiss others who may not match their level of intellect.
In reality, the world of relationships is complex and dynamic, and people are attracted to each other for a variety of reasons. The key to a successful and fulfilling relationship is often about finding someone with whom you share common values, interests, and emotional connection, rather than focusing solely on intelligence or any single trait.
