*Warren G is defending his decision to plug a brand of male sexual enhancement pills, insisting the commercial is supposed to be “funny” and the endorsement deal “is not something that dictates who I am.”

The rapper made headlines after shooting an ad for AffirmXL, an all-natural male enhancement supplement that promotes “long lasting vitality stamina.”

Warren says he believes in the brand and hopes fans will find the footage amusing, telling TMZ.com, “The commercials are funny and I meant for it to be funny. This is not something that dictates who I am.”

He adds in a statement to Allhiphop.com, “I am the original Regulator; I don’t need nothing, but I believe in AffirmXL,” while the company’s president Rob Hickman adds, “We wanted Warren as our spokesman because Warren G is a constant, has cross-generational appeal, and radiates excellence – just like the product we are presenting.”
