EXCLUSIVE

Antoine Dodson tells TMZ ... he's no stranger to the ways of the vagina ... claiming he had real-life sex with women before he switched to guys ... and says, "It was fun."

Dodson -- aka the "Bedroom Intruder" guy from YouTube -- said he's "no longer into homosexuality" ... and vows to live a straight life that falls in line with his new Hebrew Israelite religion.

We shot Dodson a few questions about his decision, here are his responses:

TMZ: "Do you believe homosexuality is a choice?"

Dodson: "I feel like homosexuality is put on people at early ages the things we see and hear and what's exposed to us."

TMZ: "How do you feel about sex with women?"

Dodson: "Sex with women is not new to me. It was fun. I did get enjoyment out of it. I was hurt by a woman as a teen."

TMZ: "Do you think homosexuality can be 'cured?'"

Dodson: "I believe when you get to a certain age, you feel different about things and things change, you begin to want more."
