What do you mean by sex and lesibian sex?

Often, heterosexual sex is when a male inserts his penis into the girls vagina. The definition could be extended to include oral and anal sex among heterosexuals. Gay sex is when a man inserts his penis into another man's mouth or anus. Of course frottage (genital to genital rubbing) and sex toys may also be involved. Straight people often do the same things with each other. Lesbian sex is when two 2 women have sex. That could involve any of the following: cunnilingus - oral sex on a woman tribadism - rubbing their clitorises together scissor sex - a type of tribadism where they intertwine their legs to rub their crotches together and are twisted 90 degrees of each other sex toys - that includes using vibrators, dildos, plugs, and other items anal sex - that includes using sex toys and oral stimulation ("rim job") To clarify, gay or lesbian sex has nothing to do with sex-reassignment surgery. Orientation is separate from gender identity, and the purpose of the surgery is to become more "normal," not less. Surgery is generally not required to be gay, unless you are a gay member of the opposite sex.
