Okay, so last night I tried to have sex with my new girlfriend for the first time, she's quite petite (5"1 and weighs 92 lbs) and is EXTREMELY tight. (She's not a virgin though.) I'm not HUGE (7.5 x 5.7) but when I tried to put it in she seemed to be in quite a bit of pain, and we ended up not having sex? Any ideas to make it a bit easier for her? And yes I did use lubrication.
