Questioning my sexuality

[SuperSteve]

As the title suggests, I've been questioning my sexuality a lot recently. For context, I am a middle aged woman, with a toddler DD, living with my ex dp until I get the keys to my new house.
I have always had boyfriends, though I guess it has been in the back of my mind that I find women attractive but I've never given it much thought until a couple of months ago when it seems to be very much on my mind a lot.
Do people just 'turn gay' (not entirely sure how else to put it, bit blunt) or am I having a mid life crisis?
Is it weird for a middle age woman to pursue relationships with other woman after all these years? Is there a dating scene for people like me or do I just need to get this weird phase out of my mind?
I always thought sexuality was one of those things that people just know, even of they chose to hide it, but I genuinely have no idea right now and I feel quite strange about it.
I'm not sure what response I want/expect? Just to tell some one I suppose

If sexuality was so black and white we wouldnt have so many different types of sexuality would we? It could be a phase or it could be something u subconsciously supressed in yourself. only way to find out, is go out there and explore your sexuality :)

My ex DH came out at 44 after 14 years of marriage and 2 kids. I think you can suppress or minimise feelings for so long, in some cases forever, but often eventually the mask slips and falls away. Sometimes it’s because you realise you have developed feelings for a particular person, or because you crave the ‘sameness’ rather than ‘difference’. If you are coming out of a long relationship be gentle with yourself and go with the flow. Don’t overthink it - you don’t need to put a label on yourself.
