Solusexual and Soluromantic
From the Latin prefix āsolusā, which means āaloneā. Solusexuals and soluromantics are attracted (sexually/romantically) to one person and one person alone (hence āsolusā).
Being solusexual and soluromantic are not mutually exclusive. Someone can be sexually attracted to only one person but is able to feel romantic attraction for others. Someone can be romantically attracted to only one person but is able to feel sexual attraction for others.
The one submitting this is soluromantic.
I had asked if there was a term for being attracted to one person alone, but nothing was turned up, an anon came up with the term.
I am grateful that I now have a word to describe who I am.
Uni- is pretty similar to this, would you like to merge definitions, or coin solu- as a separate label?
