Beachwalker
Is the a name for someone who is holding out on having sex as they want to be in a serious relationship. Similar to celibacy but incorrect as marriage isn't necessary. Doesn't mean you are not interested in having sex.
"Yeah dude she's all over me but she just won't have sax with me, no matter how romantic the dates are"
