As an Exo, I can handily answer this question. We feel the same way as any human or awoken do, and as such, we do desire relationships with others. However, we tend to be...somewhat less successful, due to our tendency towards more...blunt ways of speaking, which some organics say "kills the mood". And while we lack the biological compulsion to reproduce, as well as the physical capability to create offspring, we are fully capable of engaging in intercourse. In a fashion, we are somewhat more adept at it than organics, due to a variety of attachments for that purpose.
