Confused in the head.. 😣

So let me give you the breakdown. I’m married and have been for several years. We’ve been together for almost a decade. And I love my husband. But he’s also the only guy I’ve ever been with. I have been with two other women (hubby knows) and I enjoyed it very much. 😍 Now for the first time ever I’ve asked myself am a lesbian? Idk if it’s because I just really like girls and I think they’re so sexy and everything is passionate you know or just because my husband and I’s sex life has just been a little stale. Idk. Is that a thing? Like if you have to ask yourself then something must be up. Any insight would be appreciated! Thanks.
