Yes it's right, and It can be either a top or a bottom.
A masochist is in which sexual or other gratification depends on one's suffering physical pain or humiliation. a person who is gratified by pain, degradation, etc., that is self-imposed or imposed by others. a person who finds pleasure in self-denial, submissiveness, etc (mostly bottom). A sadist is the opposite and the dominate inflicting the pain (mostly the top). Sadomasochism is when you enjoy both.
Yes, a masochist likes to receive pain during sexual activities while a sadist likes to inflict pain on others during sexual activities.
Please correct me if I'm wrong... Masochist means a person who likes pain while doing sexual activities.. am I right?? Or not?
