What should I do??

I am good friends with a guy I go to college with and we have recently been getting naughty in the text messages department. I haven’t sent him nudes or anything like that; it’s just dirty talk. He really wants to have sex with me but I’m a virgin and I’ve sent nudes to people plenty of times but I’ve never actually had sex or even kissed anyone before. I’m shitting myself over the whole thing even though he’s really sweet and caring, I just feel really small and nervous.

If you girlies have any first time stories I would love to hear them to get some pointers 😬😬
