Celibacy is actually a way to use sexuality, if approached right. The original purpose of religious vows of celibacy was to channel sexual energy into spirituality, not repress it. Also to prevent the pursuit of sexual relationships or conquests, and the maintenance of them, from interfering with your focus on spiritual matters and study.
There was a nun who, when asked if she regretted not having sex, replied scornfully, "I'm seeing the world from an elephant's back, and you ask if regret not riding a donkey?"
There are plenty of writings by religious celibates that are deeply sexual, and deeply spiritual and mystical, too. Teresa of Avila, for instance.
All of that fits very well with Scorpio energy.
Edited to add: Assuming that is, that by "chaste" you mean celibate. Chaste can also mean avoiding non-marital sex but allowing sex within marriage, and lots of people do that for religious reasons. In that case, if they're married, they have an acceptable outlet. If they're not married, then it becomes celibacy, so see above.
