At first, Raj had difficulty talking to women

At first, Raj had difficulty talking to women. He found that drinking alcohol helped him communicate with them, but over time he worked up the courage to speak up with nothing to help him. Penny was the first woman he really communicated with, both when he was drunk and when he was sober. In season one, Raj made a snarky remark to Leonard in front of Penny, and in season The Bat Jar Conjecture, he said something to Penny before putting his hand over her mouth.
