Sexuality?

Hello there, I’m a teenager and I’m very much positive I like both guys and girls. I’ve known this for a while but just recently I had my first kiss with my current boyfriend, I love him a lot but I just felt nothing, like not even butterflies in my stomach, nothing. I love being with him and hanging out with him but I just feel nothing when something like that happens. I am still trying to figure myself out and my sexuality but I’m not sure if this could be some part of this? Send replies please, I am very curious as to what everyone else thinks
