A person that occasionally has sexual intercourse with the same sex but has no real intention of having a relationship. They "pass the time" until the real aka straight thing comes along.
A place you visit occasionally is a summer home. The same can be applied to sexuality. You'll never live there, but you will occasionally visit.

ex: She tried to tell me she was gay, but as it turns out she's just a summer homo.
