Straight (2009)

Straight is a funny story about Pinu (Vinay Pathak), a shy London restaurateur who is a virgin and has never had any sexual relations with a woman. When a stand-up comedian/cook and a caricature artist enter the restaurant, it becomes the most sought-after spot in town. Pinu wonders if he is gay as he wants to open up and socialise with others, and embarks on a quest to prove his sexual orientation.
