Dating outside of your norm!!!

Hi guys !!! So I am a bisexual female. I am attracted to women, but I mostly am attracted to men. I’ve always liked women , but envisioned myself marrying a man …. Any women that I seriously wanted to date has been masculine. I noticed that I have been attracted to women more and more lately and I’ve recently met this one girl. She’s very sweet, feminine, and sensitive . She seems to be a lot like me but also very different in a good way . She has made it perfectly clear that she is looking for a relationship and while I am too, the thought makes me nervous . I’ve been intimate with women before , but I’ve never been in a relationship and settled down with one . I guess it’s just so different for me , I’m scared that I’ll feel Iike something is missing …. has anyone felt this way before while dating someone out of their norm??? plsss no rude comments guys . I really just want genuine advice .
