Where or how do I even begin to further explore my sexuality?

I am in my mid-30s and my attraction to women have become more and more pronounced over the years, esp. in frequency. When I was in my teens there would be one or two girls that caught my attention. From my late teens and throughout my 20s I was in “full heat” and was as pure hetero as anyone could be.

Whenever I find a woman attractive it is not sexual. But I am sure it is because I have never had sex with a woman. Where do I even begin meeting lesbians? Should I try hookups first or should I try to be in a relationship? This is very much on the DL for now, I need to figure myself out before I tell anybody else about it.
