I'm just curious, besides the obvious kind of things like buying men's deodorant and cologne, showering regularly, etc. what have other people found that makes them smell less like a girl? It could be just in general, it could be a "downstairs" type of thing. Specifically if you're not on T (since that does change the way you smell).
I personally like all natural stuff and have found Tom's of Maine makes a men's deodorant that actually works for me and smells alright (therefore making me smell alright). I personally don't like really strong smells or what I'd consider unnatural smells so I find it kind of tough to buy stuff that doesn't bother me.
Since I'm into natural medicine and herbs I have happened upon some information over the years, specifically in regards to downstairs odors. Obviously if you have some sort of infection going on down there that could increase any type of smell (and of course if you do you should break down and go to the doctor about it). If you're otherwise fine but bothered by odor, you might try consuming fengreek. Apparently it regulates hormones and generally balances things. Taking a bath a few times a week in the morning with 1/2 cup of vinegar in the water could also help. The vinegar neutralizes any odors. Alternately, you can also try baking soda instead (also 1/2 cup in the bath).
It probably goes without saying but if it's shark week, you need to change things often. If you're a guy who doesn't get massive dysphoria from touching anything down there I'd totally recommend one of those cup things. I've used one for the rare occasion that my one semi-functional ovary decides to throw me a curve ball. It's actually really awesome. Zero smell and it can be there for like 12 hours. But, like I said if you have trouble with that area, the deployment and extraction of the thing might cause you much grief. But it might just be worth experimenting with as well. If it's going to be awhile before you're on T, the upside of these cup things are: get through sticking it in and then you can forget it for the whole day, no more uncomfortable trips to the store to the lady aisle (the thing's made of silicone so you wash/sterilize it and reuse it), you can feel more like you're in charge rather than at the mercy of your body, and you could totally pack while using it.
That's all I can think of for the moment.
