In a relationship and I want to see other people

I’ve been in two serious relationships. I dated my ex for 7 years and I’ve been with my current boyfriend for almost 3 years. I met my current boyfriend shortly after my ex and broke up. I feel like I haven’t had time to be single and get to know myself as a person. Sometimes I just want to have fun as a single person bc I never really got to experience that. I’ve been in serious relationships and feel like at this time in my life I want to experience more of life.. but then again I’m 23 and feel like I’m too old to do that.. I also know that my boyfriend is the one, it’s just I feel like I have the rest of my life to spend with him but I don’t know.. I’m so confused

Is this wrong?
