Pectussexual is the act of being sexually attracted to the upper part of the body, such as breasts and chest, but not the lower parts of the body such as genitals and buttocks. It is a term for people who enjoy the idea of upper body contact but experience displeasure or repulsion to the idea of lower body contact.
This term can be combined with other terms, for example, one could be gay and pectussexual.
One could also be pectusromantic, pectusflexible or pectusflux.
The term 'pectussexual' is derived from the Latin word 'pectus' meaning 'chest'.
