Jezus you guys are so sad!
OK advice from a woman here:
1- Be sensitive when you approach the subject (DONT just push her head down as advised)
2- Lie. During a make-out session as things are progressing, you want to suggest it but tell her you've never had one she's special, yada yada yada... Act inexperienced, Chicks like the be "the first"
3- When it happens, good or bad, try to have the most over-the-top orgasm possible. Moan, scream, shake whatever it takes... make her feel like it was amazing to ensure they continue in the future.
BOL on your situation.
PS- She's gonna find out about your alcoholism soon enough so if you really so like this chick you're gonna have to come clean or turn her into a drunk too.
