Sean Penn was so excited about sharing his first smooch with a dude he sent a text to ex-wife Madonna just to brag.

Penn shares an on-screen liplock with Spiderman star James Franco for his role as openly-gay San Francisco politico Harvey Milk in the upcoming biopic Milk.

James says: “After our kiss Sean texted Madonna and said, ‘I just popped my cherry kissing a guy. I thought of you. I don’t know why.’ “
