A male who has a preference for platonic "fraternal sibling" relationships with women as opposed to sexual relationships.

The "little brother" may not necessarily reject a sexual encounter with a woman with whom he has developed a "fraternal sibling" relationship, but it is not the primary motivation for initiating or continuing the relationship and generally not the desired outcome.
"Don't start unless you're up for it all the way. I don't need another little brother".
