Can you get a sims download that changes what they say?

Like you know how you click on the sim and you can kiss them tender and stuff. Well it gets boring with the same options and so i have been using thesimsresource and mod the sims. And i was wondering if you can change that with a download to add more options. Or change the options for when you wanna do it if you could change it to a more realistic one. Thanks so much!
