The phrase "gets it up" is a colloquial way of saying someone is able to achieve an erection. However, for those who prefer a less crass expression, there are several alternative synonyms that can be used. One such synonym is "achieving tumescence." This is a formal medical term but can be used in a more polite manner. Other synonyms include "attaining an erection," "becoming erect," "getting hard," and "getting stiff." These phrases are all more acceptable in polite company and can be used in both medical and social settings. It is important to know that there is no shame in experiencing erectile difficulties, and there are many options available for those seeking help.
