When an individual, who is too fatigued to engage in sexual activity themselves, lay spread out on the bed for their partner.

The term "Starfish" comes from the shape that the individual makes when they spread out.

Music so good it could elicit sexual arousal.

When an individual is too intoxicated or tired to participate in intercourse with their partner they simply lay on their back outstretched to resemble the same shape as a starfish and let their partner do all the work.

Starfishing- The act of two people spreading their butt cheeks apart and touching and/or rubbing each other's assholes together.

Yes, it is a thing. Some people will state that this isn't possible. That only means that they have tried it.

The act of sprawling out in bed, taking up as much space as possible, immediately upon the departure of your significant other, fuck buddy, or one night stand.

The act of being a lazy, boring, intoxicated lay. Pertaining more specifically to when your arms and legs go limp just before you pass out.

When your significant other is mentally willing but not as physically enthused to perform the act(s) of love and does so anyway in a passive mode.

** Position **
Usually missionary, but hey, maybe you guys want to watch TV together too...

**Context**
While a deal-breaker in the new phase of a relationship, StarFishing is an acceptable mitzvah for the married partner. It's also an opportunity, thru proper application of experience and technique to elevate the session to another level. See fuckortunity
