Fact: One of the things that men want in bed is spoken in "dirty" words.
In a previous article , it is written: It is not necessary to tell everything that is going on, but will be surprised with the effect of having some dirty words at the right moment. Not everyone is comfortable doing this, but there is no need to go far from the comfort zone. Words and expressions like "lagem", "feel very good" and "stronger" can work very well. Just do not show much specificity, "Confirm that your penis is in my vagina" will not work for anyone.
Based on a poll of some days ago, 84% of voters said they "talked with erotic messages". Likewise, the vast majority claimed that they "speak dirty words".
However, as you read it in the headline, this article is for all those who have such a discomfort.
Note that no one compels you; so if you do not want, there is no problem. If you are not 100% involved in why you do not trust your partner, it is hard to feel comfortable with such a situation.
If you really feel you can practice it, first talk to your partner. Start with sentences describing what's in your mind. So you can start the parade.
To enrich "vocabulary", you can read erotic books. The first time you go out with messages since you may feel uncomfortable in the face. Speak aloud what you like and what not.
