I think meds are the reason I am unable to have an orgasm.

I agree. And it seems mean enough to have to be on medication already

When I was younger I was on SSRIs, but was also a young woman, so my natural estrogen levels must have been higher than they are now, when I am 40.

I learned in college that women with high estrogen levels are highly fertile and their outward appearances (large breasts and hips) are indicators of that fertility and make them attractive to straight men. But it sucked to attract everyone and feel nothing in return.

I've read and heard that (the fertility thing). Regardless of what science tells us, I believe that it is questionable. First off, I know plenty of women who have a Rubinesque build and have pcos and other "female" issues that curvier women are more likely to have, and those issues often interfere with fertility.

Secondly, I know plenty of women who are (or were, during childbearing years) tall and slender and they easily conceive. The latter description fit me and all I had to do was say the word "pregnant" and I was...5 times, first try each time.

With regard to men being attracted to a woman with a specific build, I do think that many men are inclined to prefer women who are curvy. But then, too, I know of other examples...a man I was involved had a thing for women who were so slender as to appear child-like, or to be more polite, "built like a model" - he referred to such women as "graceful." (I always thought the guy was obsessed with himself staying youthful, but that's beside the point). I worked with a man who found quite plump women pleasing to look at, or be with. I suppose it varies from man to man, culture to culture, era, etc.

Actually, hormone levels for a normally developed human being fall within a specific range. So really, they can't go very high or very low.

With regard to men/women finding you attractive, but you not feeling anything in return, that sounds sad. Even depressing for you, as it could really interfere with having a relationship.

I also thought I was bisexual. I have only been with men, but never had much pleasure from it. I now think I am a lesbian. But have yet to experience sex with a woman.

Heck, woman - go for it! That's my thought, anyway. I mean, if you have the opportunity, at least give it a try and see where you're at.
