The surprisingly scary parts of giving someone dominance over you

In my personal life, I'm extremely independent. At work, with my friends, and in my free time too. I have a Dom that I have very casual playtime with and nothing else and that's great so far. We're friends and have fun.

But I have a relationship with a Daddy that is starting to become a little bit more serious. I'm laying in bed thinking about meeting up with him and the thought of someone doing stuff for me like buying me dinner or even a cup of coffee (his words and offer) is kind of freaking me out. Actually really freaking me out. I don't usually let anyone buy me anything. I usually pay for half or everything because I don't trust people to not hold buying me things over my head.

Like "oh yeah, you can totally leave my ass covered in hand prints and bruises and I'll be on my hands and knees for you on a leash. You can tie me to a bed and refuse to untie me until I'm overstimulated from too many orgasms" That feels so easy compared to "I'll accept you buying me a bottle of water or juice and it won't make me uncomfortable at all"
