If you didn't consent, yes, it can be considered rape. (I say "it can be considered" because some people don't consider themselves victims of rape if they did not fully consent, but if you felt he shouldn't have, he shouldn't have and it's rape. Period.) Sleeping people cannot consent. Intoxicated people cannot consent (although not everyone knows that).

There are also two other forums on PC that might be of interest to you: namely the Post-Traumatic Stress forum (
forums.psychcentral.com/post-traumatic-stress/) and the Survivors of Abuse forum (
http://forums.psychcentral.com/survivors-abuse/). You're welcome to post on both (as well as here, of course).
