Sub drop.... Is that what this is?

So. I e never really been in the lifestyle. Im familiar with certain things though. I like to research. When I mess with this guy....the feelings are incredible. He gets me in a way that always seems so profound. But when I'm without him I feel lost/depressed. Like I'm just waiting for him to come back. And he said I need to get used to being used. It's all apart of his 'master plan'..... But I just ended things because I can't survive on sexual/emotional crumbs.

So something occurred to me tonight... Is that "sub drop" that I've been experiencing??
