Committing to being a boyfriend

I have had two dates with a women over the last two weeks. I enjoyed both dates. I did not feel a spark of instant overwhelming attraction on my end. We do have a lot in common and can see myself enjoying more time with her. She indicated that she really wanted to make out with me. We kissed on our last date. I was hoping that might make me feel the spark/ chemistry for her. It was a nice kiss but when compared to my past relationship I did not feel the instant overwhelming sexual attraction for this one. I'm trying not to compare future dates/ relationships against my last one because it was something I had never experienced in my life in terms of sexual tension chemistry. I'm trying to be open as I may never experience that again. This new women has indicated her intentions are to have a boyfriend. I can tell she is super in to me and would agree to be in an exclusive relationship with me right now if I asked. I'm not there yet. I don't know if I'm ready for that. Part of me wants to continue seeing her to see how things develop and because I enjoy my time with her. On the other hand, I can tell she really in to me and I don't want to hurt her if things don't work out. I also want to keep my options open to date others if the opportunity presents itself. I'm still swiping on the apps. What's the best way to proceed with this? Tell her I enjoy our time together but not sure when or if I can commit to being her boyfriend any time soon? She's not asking yet but I know it's coming. I'm a total rookie in dating so I am trying to date multiple women until I feel the spark I am looking for. But I don't want it to ruin my chances of a good new relationship if I never feel that spark again.
