You always remember your first ... especially when he's a super famous NBA player -- so says singer Teyana Taylor who just revealed that Brandon Jennings recently swiped her V-card.
Taylor -- who's signed to Kanye West's record label -- appeared on the Breakfast Club on Power 105.1 this morning and talked about her fizzled relationship with the Detroit Pistons player.
During the interview, Taylor revealed all sorts of intimate details -- including the fact she made Jennings wait two years AFTER they were engaged before she gave up the "goodies."
Taylor -- who's 23 -- also says she hasn't slept with anyone other than Jennings ... but says, "When I'm ready to have my second ... I'm gonna do that."
Jennings is now dating one of Taylor's ex-friends -- but Teyana says she's not bitter at Brandon. In fact, she says she wishes him nothing but happiness. As for BJ's new chick, Taylor says she feels betrayed.
One other thing -- Taylor also shot down rumors she's dating Colin Kaepernick ... but did say, "That's my homie though."
