I honestly don't know why they wouldn't tho, because I wouldn't need to be a girl to have known the experience of the swimsuit was amazing. But my god was it exactly that. It was incredibly comfortable, and it made me feel more like me. It also made me feel a little bit sexy. The whole day, I was just...exuding an aura of something I rarely display, of just an energy that I only display in my most euphoric moments. The moments where not a touch of gender dysphoria hits me, where I feel like I look like a girl.
While I loved it.
It was not without its downsides.
1: It was a bit warm. This is pretty unavoidable. The only things I was wearing on my torso (the area which was warm) were the bathing suit and my lifeguard shirt. I obviously can't get rid of my guarding shirt, so...not much I can do to be cooler when wearing the bathing suit underneath. Not much of an issue, given that I am skin and bones so rarely overheat anyway.
2: Some parts were initially a little itchy. I imagine that this is a byproduct of it being a new swimsuit though, because I'm pretty sure that every swimsuit I've ever worn has had that problem when they were brand new.
3: Some parts felt a little tight at times and some areas didn't quite stay in place properly. I believe the two are related, in that the tightness likely came from areas of the suit slipping out of their proper position. This is not something which is very fixable because it's an issue you deal with, with any given article of clothing. No piece of clothing is perfectly tailored to your exact measurements (unless of course...they are, but those are like...$200 business suits), and swimsuits are no exception to this. This is something which happens for all of my clothes, so isn't an issue specific to the bathing suit.
4: The straps at times seemed to be pushing in, in a way akin to having worn a heavy loaded backpack for too long. Especially the left shoulder which was bothering me about 50% of the time. Half of this can be attributed to the above--the suit slightly shifted out of the proper position, I didn't really notice this in the area it slipped, but felt the slippage in the form of the shoulder straps.
But mostly? This wasn't creating a problem; this was alerting me to an existing problem. Even without the bathing suit's straps, my left shoulder was suffering from a condition which I'd call some combination of "tight, sore, tender, stiff, fatigued". This is not a new issue. It's a known problem I frequently suffer from. From the base of my neck to my deltoid muscle, my left shoulder flares up on occasion to have that issue.
The only fix I have to it is trying to stretch the muscles, massage them a little, roll the shoulder, hyperextend it, basically try every trick in the book to loosen them up, to remove tension from them, to basically make them...not bother me. So, again. Not a problem related to the suit.
Noticing a trend? Yeah, basically, none of the problems were due to the suit and all of them are things which can be managed and were minor nuisances, not real problems. Things which are annoying, but which aren't detrimental and won't consistently plague me especially not now that I know of them (and even if they do, given time to break the suit in, they'll go away).
There is one problem which is due to the suit tho.
One which will, presumably, go away after a while, but which is still a little inconvenient.
5: So sometimes, I can randomly be aroused by thoughts which aren't sexual at all. These arousing things strike randomly, where I basically go, "what the hell, body? There wasn't so much as a single sexy thought in there, not even a kinky thought, not anything which is a fetish, so why are you being aroused by that?"
When I was initially putting the suit on, this hit me hard. (Haha. Sadly.) If I had to guess, my guess is basically that I suffered from Distracted By My Own Sexy, in that I literally said to myself, "Okay, yeah, I get it. I'm sexy like this. Now shut up. We've got work to do." And at the end of my shift when changing out, while I was wearing nothing but the swim suit, I ended up going for a while, "Okay, fine. I'll take some time to appreciate that, yes. I am sexy in this. I have the time to spare. But you need to get used to it, body, because this is going to be the new me."
Because, yeah. I feel incredibly sexy in it. It fits me, it looks good on me (well, as far as I can tell, anyway; I have no mirror so hard to say for sure), and I feel a lot more like my femininity is more on display while wearing it (even though it's not actually visible). I feel like I am more openly displaying "hey I'm a girl" while wearing it and that feels so good. Everything about it is amazing and it is incredibly comfortable.
I do think that eventually, my body will adjust to that and it'll stop happening. (It's honestly annoying and I feel a little annoyed/guilty that the arousal happens when putting it on/taking it off. So hopefully it's a temporary thing related to it being a new change that the arousal is just extreme excitement about.)
So glad I took the plunge and made that buy.
