When lesbians have sex, they tend to "eat" each other...what are the effects of doing that?:-)
Typically nothing, but certain STD's such as HPV can be spread through oral!
Hopefully extreme pleasure and lots of amazing orgasms. You also need to be aware of STDs as you do with any type of sex. And BTW lesbians do a whole lot more than just eat each other out.
It fells grate that is y we do it. It is no different than a man doing it
