Hi there wildmarshmallow, and welcome to Scarleteen!
Congrats on the new date!
I'm sorry to hear that the things he's saying make you feel uncomfy. I think it's totally understandable that you're not quite ready to be sexual with him after just 5 days (or any amount of days - your own readiness and comfort is something that you deserve to go through your own pace). I'm glad that you're able to recognize that in yourself, and that you're thinking about how to communicate about it.
I want to turn your question back to you a bit - how have you responded when he's said these things to you? Has he noticed or acknowledged any discomfort or not-so-thrilled feelings from your side?
Also, if you haven't read it yet, you might find both Ready or Not? The Scarleteen Sex Readiness Checklist
and Whoa There! How to Slow Down When You're Moving Too Fast
helpful in thinking through how you're feeling and how you might respond. <3
