sex friend 

A couple (if you can even call it a real relationship) who's only real redeeming quality is to fuck each other. These "couples" often soon break up shortly after meeting. The female loses interest as she expects to be brutally fucked every night. These "couples" often tend to ignore family members, do drugs (not always but very common upon the culture), heavy music (loud music that has no fucking value what so ever).

A sex friend usually leaves quickly and is a bad thing to see in a relationship.

Girl 1: "How's Jonah doing?"
Girl 2: "Oh, why do you ask? He's just my little sex friend anyway."
Girl 1: "Oh.."

Jake Paul: "Alissa was just my sex friend. Tessa is better anyway."

Best Friend Sexual Relationship(BFSR) 

When you are really close friends with someone and you guys have the same benefits as a FWB relationship. The reason why this relationship is different then a FWB is because the two of you do HAVE an emotional connection as well and physical yet dont wanna be in a commited relationship together. although you are commited as friends. Just not as partners.

also when your in this kind of relationship its rare if other people know about it.

WORNING! because you guys are such close friends there is a huge possiblity that one or the other will want a commited relationship.

EXAMPLE:

In the car coming back from SEA WORLD (after dropping off other peoples IDK)

FRIEND1(female): man that was a ton of fun we should do that again, you should have seen the look on your face >.< when you got soaked on that ride! *LMAFO*

FRIEND2(male): OH! get off it! you should have seen the look on your face, you looked like your head was about to be chopped off or something!

FRIEND2 PULLS TO THE SIDE OF THE ROAD

FRIEND1:hello dont tell me you forgot where my house is ;

FRIEND2: no....i just feel like kissing you.

KISSING INTHE CAR ^-^ YUPYUP hence Best Friend Sexual Relationship(BFSR)
