it has alot to do with heightWhat does sex skills have to do with height. And 5'5" is average height, it's not short.
sexual attraction is based in the brain
the response to sexual interaction is based on what the brain relays to you about what you are attracted to most
so if i am more attracted to taller females then interaction with a shorter one would not the the same level of pleasure
also shorter legs means no elongated muscles to work her kegals
and usually shorter women have a smaller clit and less sensitive nerve receptors so the whole process is less enjoyable
