Questions about making sexual demands

I have known my girlfriend for nearly 200 days, and I fell in love in 100 days. After that, she mostly disagreed when she made a request, but she also agreed to my request the next day.
However, recently I made these requests and she disagreed, so she always feels embarrassed because of these requests. She thought it was absurd for me to make these requests, so she asked me: When you talked about friends with me, did you just think about these?
So I am very distressed. I bought a real doll in Myminisexdoll

Excuse me, is it normal to require sex in this situation?
