Roleplaying sex

what is a good way to start roleplaying sex for male and a female character and what do you say for there urges and when they cum or have an orgasm.

for a male- I am male so usually I start out with *Kisses you, hugging you tight while running my fingers ever so gently up your back.*

as for male urges a just say *Grunts panting heavily as I arc my back shooting string after string of cum into your tunnel*

For a female- I'm not female so I've never had to do this part. so I can't help ya.
