How does Deontay Wilder feel about Tyson Fury's claim that he's masturbating 7 times a day to prep for their big rematch?! He thinks it's HILARIOUS!
"I mean, enjoy yourself," Wilder said to his heavyweight rival ... "Just use the proper lotion!"
Of course, Fury says he's giving himself TONS of self love before their Feb 22 fight to get his testosterone levels up ... claiming he'll take any edge he can get!
Wilder thinks Fury is joking -- because 7-times a day is a tall order for anyone!
"Whatever he says is for entertainment or whatever," Wilder says .
