People may also remove some or all of their pubic hair for aesthetic or sexual reasons. This custom can be motivated by reasons of potentially increased personal cleanliness or hygiene, heightened sensitivity during sexual activity, or the desire to take on a more exposed appearance and visual appeal, or to boost self-confidence when affected by excessive hair. Moreover, unwanted or excessive hair is often removed in preparatory situations by both sexes, in order to avoid socially awkward situations. For example, unwanted or excessive hair may be removed in preparation for a sexual encounter, or before visiting a public beach.
