Simply the fact that you don't have a rax asap is enough for a player that knows when buildings are up.
No you don't lose to a double musk. 5 huss+mm will hold rape 10 musk np. And then you have time to build the raxes (and you can just build a rax if he doesn't push).
A bow/pike rush might beat that, true, but unless you're garja, you'll remember that you have a native scout. So seeing no vills on gold, no tp a 2 raxes, you'll guess it's a bow rush (again, that is assuming you have a decent game knowledge and the ability to adapt).
You hold a russian rush with 4v/700w without any problems, that's what we all used to do.
And well, the iro rush is imba anyway, but 4v 1st is better because it allows you to punish a greedy play, and vs the rush, you just need to raid and hold with the vills, some musks won't change the done.
If you have some issues vs these rushes, another tip I can give you is to start with a rax.
Players who don't have great defensive skills often find a musk start easier.
Conclusion: If you have hard time vs no eco rushes,
1) Scout more. Use your native scout and your explorer, check if they build a market, a TP, if they have vills on gold etc. With experience it will become easy.
2) Try to find a friend who's at your level and ask him to rush you, then, try to hold and you'll improve your mechanics. I'd recommend you to ask KingRichard and ibero83, they're good training partners.
I hope this helped, if you don't become good in 2 weeks it's normal, keep practicing and you'll improve!
