What’s my sexuality???

So I have always loved the idea of being in a relationship getting married etc. but when it comes to dating i don’t feel comfortable. I am straight (maybe slightly bi curious). I had a pretty serious online relationship where for the first day i was so anxious about dating anyone and i considered breaking up with him i only didn’t because i knew it would upset him so i kept it going and after a little while i became fully comfortable with him an i could be myself, then i became extremely attached to him and i would want to talk to him all the time and even when things started to go down hill and i knew the relationship was bad, i still wanted to stay because i loved him and i didn’t care, as long as i had him i was fine he was like my comfort person yk(we lasted roughly 6months). and i thought that i had all that anxiety because it was my first relationship (im diagnosed with anxiety btw). Now i have gotten into an irl relationship and I just feel really anxious and im scared of being in the relationship, i honestly hate the idea of all romantic gestures and gift giving, i absolutely despise receiving gifts. I have only been in this relationship a couple days but i don’t want this type of relationship with someone im not 100% comfortable with and myself around. He’s really sweet but i just hate being in relationships at the start. Even after i lost love for my last boyfriend, i stayed because i was way too emotionally attached to let him go, i have considered that i might be on the asexual spectrum but since there are so many different orientations im not sure if im actually on there or not, what would you say? If you need any more information just ask im sure there’s so much i haven’t said, i just want to know how to identify because then it would help me live a happier life yk
