advice on compatibility

Hi, I need an advice on a situationship that I have right now. I’m 22yo. At the beginning i’d like to say that i don’t have much experience with relationships. I was in one relationship that lasted barely two months and was long distance, also quite toxic :(

So a bit over a month ago I met this girl, we’ve been meeting for the last couple of weeks and I really like her. I feel like she gets me and i find her very attractive. She also has many personality traits that I value. The thing is that there were some situations that made me think we’re not sexually compatible.

I don’t know if she absolutely cannot flirt or if she’s shy, but it’s definitely something that makes me confused. Yesterday i was getting ready for a birthday party that i was going to so i sent her some pictures of my outfit and she reacted only with "nice, pretty" while my friends were like "omg you look so hot". It is also the way i would react if someone sent me this kind of pictures because i know it’s nice to hear those things. I don’t know if it’s a mistake to expect from someone the reactions that i would have, because everyone is different. We’re going slowly and I am really happy about it, but I feel like I’m the one that initiates things. Last week I kissed her first and since then we have kissed only once cause i don’t want to be the only one who initiates things. She has said that she had 7 sexual partners so it’s not like she’s inexperienced. Also she is a very submissive person and I like to be dominated.

I really like her, she seems to be very healthy if it comes to relationships and i really haven’t seen any red flags so far, but i’m quite scared to engage more because I’ll be hurt if it doesn’t work out in regards of sexual compatibility and we’ll have to end this.

Like I said i don’t have experience with relationships so it’s hard for me to figure out where we’re going with this and if it has any potential. I’d appreciate any advices or you sharing some experiences. Thank you for reading :)
