Scourge,
I'm going to take a different tack here. Seeing you have a nearly non-existent profile, (which seems to be a common sin here) I'm going to give you the benefit of the doubt, and assume you're being mostly up-front with us. I agree, 18 is a bit young to be considering drastic moves such as those you contemplate. HOWEVER, that wouldn't exactly be unheard of. Being "only" 18, maybe national news and events don't draw a lot of your attention, but as a person who is afflicted with the "condition",(for lack of a better word) that you are struggling with, it may interest you that "don't ask don't tell" has been repealed and done away with. Sure, if you go running around drawing attention to yourself, you will definitely be spotlighted. And, unless you have an overwhelming desire to forfeit most of your own thought processes, for god's sake, don't enlist to be a "jarhead". If you're as "femmy" as you say, (which is an oft-exaggerated comment) I'd remind you that there is the Coast Guard. Outside of the rescue swimmers, you don't see a lot of hunky macho types in their midst.
That aside, you're not going to get a set of breasts on $100 worth of PM. So, forget about a "booby test-drive". Ain't gonna happen. I will, however tell you that were I you, I would go ahead and take the PM that you have. Take 1-2 capsules a day. The reason I suggest that is to see if it provides you with a sort of "calming effect" that may make your issue easier to deal with. Even finding out if that happens will take more than a week. If that works, and enables you to see that it can be dealt with, then I assure you, that should you want to do the things you mention, you can do it on a minimal dosage with probably few physical changes. You're full of (possibly) raging hormones right now, and that only serves to complicate your problem. I'd give it a try. You already spent your money. If you get any private messages offering to buy your PM at a discount, (hey, it happens) ignore it and use it. You may have doubts later if you don't. At least, I know I would.
If you're worried that PM may "re-wire" your brain, don't worry about that. My opinion is that PM performs a sort of "balancing act" that is only there as long as you take it. Actually, I think, (here's one for the rest of you to sink your teeth into) that brain-rewiring is an overly-bantered pseudo invention from someone attempting to sound impressive. While PM will, in sufficient doses, and over sufficient time, make physical changes, (and some of these may compound themselves to cause further unintended progression), I don't think it will make a transsexual out of someone who is not already pre-disposed as such. I feel that PM is simply an "urge-suppressor". While that term is not as sexy as "brain-rewiring", it's a lot easier to define, and understand, and the result is the same. When the "suppressing" factor is removed, the urge comes back. Re-wiring implies that a permanent change has been made. I've never re-wired a house only to have to come back a month later and re-wire it all over again. In the military, fire suppression is only effective as long as you have lead to throw downrange. When you stop blasting, they start shooting back.
Long story short, try it. Just don't get crazy-stupid and start taking 6-8 capsules a day. That would only compound your current situation, especially the home life. You may (hopefully), find that 1-2 daily allows you to cope with your quandary much better. I'm not going to sugar-coat it and say that will solve all your problems. It may, but on the other hand, you may indeed discover that you want to go further. That's a whole different situation than the simple confusion you're dealing with now. And will require you to re-define everything in your life. Your decision, but it will be interesting to hear how it turns out should you give it a try. Take care!! Patti
