Is it normal date someone who gives me no butterflies

I always date someone who gives me butterflies but honestly my anxiety issues are too bad for it to work. And I never felt that for anyone who was good for me or made me safe.
Now I am dating a guy who seems pretty into me but I dont feel anything intense.He is similar to me, has anxiety issues and has been misunderstood a lot. We are weirdos and he gets it.
We have now dated a month. He is interested in having me meet his parents. I have never introduced any man ive dated to my mother before and she is a bit upset by that so im going to introduce this one. He is a sweet guy and caring and he is kind of cute but I feel no butterflies. Its nice because I am not sad when we say goodbye instead I can immadiately focus on other things but I look forward to seeing him again. I guess I must feel something because im not the type of person who can stand the company of someone else easily, I dont even want to see my friends often so yeah. Is it a good idea to get involved with someone who gives no butterflies or is such a feeling necessary?
I feel good with him though. We can talk about anything and we can be quiet comfortably.
