After all, people who are uncomfortable asking their partners to wear a condom may be at higher risk of having unprotected sex and exposing themselves to sexually transmitted infections.
Nonetheless, that difference doesn't fully explain why the sexually chatty are happier with their erotic lives.
"Even if you just have a little bit of anxiety about the communication, that affects whether you're communicating or not, but it also directly affected their satisfaction," said study researcher Elizabeth Babin, an expert on health communication at Cleveland State University in Ohio.
New research finds that comfort with sexual communication is directly linked to sexual satisfaction.
People who are more comfortable talking about sex are also more likely to do so while having sex, the researchers found.
Communication during sex, in turn, was linked to more sexual satisfaction.
Nonverbal communication was more closely linked to satisfaction than verbal communication, Babin reported online in August in the Journal of Social and Personal Relationships. "It could be perceived as being less threatening, so it might be easier to moan or to move in a certain way to communicate that I'm enjoying the sexual encounter than to say, 'Hey, this feels really good, I like that,'" Babin said.
