[prostatenipple]

I've been curious about E - I assume it's not something I can just take for a week or two to see how it works for me?

I should have expanded on this ^^^^^
I just don't think I can go to my GP and ask for 2 week's supply of estrogen, just to "try it out". I mean, it would probably raise red flags for them (especially because I'm on TRT), but how else would I know if it fits me better and whether I'm actually trans (that test in the other thread suggested I might be).

So the only way to do that, is via phyto (like PM), or underground sources.
If the NHS made it easier for people to try either way (they probably still want to make sure you know the risks / side effects etc), it might help people work out which way they want to go: stay male, or get closer to transitioning. But at least it wouldn't have to be all hush-hush with shame and embarrassment.

But hey, it's the NHS after all (they won't give T to a male that wants to be a male, until their T levels drop so much that they are < 8 nmol/L usually, like an 80 year old male level, for like a 30 year old). So I'm not convinced they would be sensible with my proposal above.
