Straight edge sex takes place between two people, one or both of whom are straight edge, who have sex because they care for one another rather than because it is available.

Contrary to what has been written, straight edge - see also straightedge and sxe - people do often have premarital sex (though some do not), but abstain from casual sex without a committed relationship and/or deep emotional bond with the person they are having sex with.
Straight edge sex is an expression of love between two people, not just a "good time" with an acquiantance.

1. The act of a man inserting his penis into a womans ass. Not to be confused with gay butt sex.

2. (Rare) The act of a woman inserting a dildo into a man's ass. This is considered to be a form of gay butt sex in some circles.
1. Harry was tired of Sarah's loose vagina so he decided to stick it in her butt for some straight butt sex.

2. Sarah rammed the 10 inch blue dildo up Harry's ass for some straight butt sex that some would consider kinda gay.
