Thoughts on navigating sexuality after marriage? (31F, 36M)

So I (31F) have been with men exclusively since I first started dating as a teenager and have never been attracted to the same sex (truthfully the female anatomy scares me a little). I’m also married to a wonderful man I’ve been with 6 years (dating 4 years, married for almost 2).

Very recently, as of the middle of the year, I’ve noticed that I’m more frequently noticing certain women (masculine-presenting/tomboy type, in case that matters). Not in a sexual way like I want to sleep with them, but there’s definitely an attraction. I’m confused because I’ve been 100% straight my entire life, as well as immensely guilty because, like I said, my husband’s a marvelous human being and he’s everything I’ve wanted in a man. But I’m wondering if this is just a fleeting curiosity or something I should express to my husband that I might want to delve into deeper.

Have any of my fellow ladies dealt with this before? Any insight and feedback would be appreciated!
