Lesbian Exclusive Exchange

Us girls were taught "If you can't say anything nice, keep your mouth shut." Fuck that shit;) Girl, you have got to learn to talk dirty. It's an art form that does wonders to get (or keep) that hottie in your bed. Oh, so now you want to... but don’t have any clue where to start? Don’t fret my pet, it's not that hard to learn. And don't concern yourself with the subsequent hysterics you’ll trigger when she tells her friends about your goofs.YES, there may be gaffs & giggles, but humor is good for relationships too.
Dip the Toes
Communication is key to good sex. We should all know this by now, yet we still don’t practice it half as much as we should. The first step to introducing something new into the bedroom is to test it in casual conversation. Ask something like: “Have you ever talked dirty before?" This gets the idea into her head and she’ll ponder it after you mention it. She may even discuss it with her friends to see what they think. It is possible that she will flatly refuse to entertain the idea. In which case, it’s best to drop it like a lead weight. If she's that uncomfortable, she is not likely to change her mind anytime soon and any attempts will probably turn her off. Talking about what we want in bed can be difficult. Requests can be misconstrued as “you are not good enough,” when in reality, they are essential to healthy sexuality. Statistics say a whopping 80% of our sex lives takes place in between our ears. So, talking dirty can be a headboard-busting turn-on for both partners.

There are three aspects of successfully integrating dirty talk into sex play. The first is content. It’s supposed to turn her on, not make her cringe or burst out laughing. The second is delivery: tone, volume and proper warm up are all important. The third is to avoid being rude or crude so you don't get bitch slapped. Here’s a tip: Don’t mention her sister.
 
Dirty Dos
Read
Erotica can be incredibly stimulating and is a fantastic way to spend an hour, whether it leads to sex or not. There are good lesbian erotic writers around, but finding something she will like can be a challenge. Find something that's not trashy, it's less likely to offend. In reading to her, practice your sexy voice.  
Swear
Dirty words are definitely a part of lesbian culture.Swearing can be hot when talking dirty in bed. The very words: pussy, cum, squirt spur on the raw purity sex acts. It can also bring out another side of us. If your girl is sweet and polite by nature, expressing her dirty side in bed can be a real buzz for both of you.  
Speak
English is not the most romantic language on earth. French, Italian or Portuguese sounds so much better. Having words spoken to you in a foreign tongue during sex can be a beautiful thing. Learn to say simple phrases like, I love you and I want you and I want to fuck you and incorporate these into your dirty talk language.
Dirty Dont's
Don't do friends or family
References to her family or yours are strictly out of bounds. Don’t mention anything about her super-sexy friend either or she'll pull those panties up promptly.
Don't do other women
Don’t bring up the topic of other women unless she specifically requests it, otherwise it could make her feel insecure. Insecurity is not an aphrodisiac. However, it is quite possible that your partner may want to hear you talking filth about another woman. It may turn her on to know that other women want you and that you want them. Be sure before you venture there.
Don't do clinical or childish
Clinical terms will sweep the sexy right out of the moment. Saying your vagina is lubricating seriously kills the moment with images of the gynos office.  This applies to all parts of the anatomy, with the possible exception of the term breasts.Try something like, "my pussy is wet for you" instead. Immature terms are a turn off too.  The words “boobies” or ”jugs;” are simply not sexy.
Time to Deliver
Voice Choice
What is sexy to you? Low & deep... a breathy whisper? Your normal talking voice or a new persona? Play around with a few and choose one you like that feels comfortable, not forced. The benefit of having a special dirty talk voice is that when you are on the phone with her and you use your sexy voice, she will associate that voice with (hopefully) raunchy, exciting sex. 
Warm Up Drill
First, make sure you are both in the mood. It is easiest to start talking dirty when you are actually having sex. Usually, you will both need to be somewhat turned on for it to work, so no skipping foreplay. Whisper a couple of things in her ear and see how she responds, just to test the waters.  
Start Your/Her Engine
A good way to start is by simply talking about what you are doing and how good it feels, but don’t drown on about it. A play by play of the action can be a turn off. Just say a few things, like: “Your skin feels so good” or “I love when you play with my nipples.” Also, keep in mind that some women can get self-conscious when comments about their body are made during sex.  This dialogue has other benefits too. She’ll get to learn more about what you like during sex and it will encourage her to speak up too. 
  Repertoire 101
Be creative and vary your dirty talk; nobody likes a broken record. Practice at it. Once you are more confident that she's into it you can get her to join in -- you may just find her cursing back at you.
Review
Save the analysis for later. Discuss it when you’re fully clothed and watching TV or making dinner. This way, there is far less risk of damaging egos. You can talk about which parts you both liked or didn't and why. Keep the discussion lighthearted and fun. Remember, anxiety or fear may manifest themselves into laughter. Talk like adults, be honest and encourage each other.
