Hola Matias
(Yeah Baby!!!). 
Welcome aboard the B & B (besides being enrolled in the fictional, sacred and utopian Order of Shavedom). Please feel free to come up to the promenade / sun deck & 'sit-a-spell'.
Sounds like your off to a great start (and good ridance for your electric shaver), and yes,...this Forum has the knowledge, ideas, and alround 'know-how' to assist in your Wet-Shaving experience. In a nut-shell...your 'gonna' love it here.
My humble advice is to purchase a Razor Blade Sampler to see what blade would be a good fit (mild, moderate & aggressive, ect...), for your face and Razor. By the way, I happen to like Shark Super Chrome with my DE Merkur's 23C & 38C razors.
"Merkur; Solingen quality, Time-tested Tradition with Modern Design". 
If you do get a Sampler, my advice is to try 2,3,4 or 5 blades (however which amount per blade brand), before moving on to the next blade.
Also, long ago when I received my Sampler, I started a Thread entitled "In what Order should I test these Sampler Razor Blades?", and the best advice was from member Optometrist a.k.a David who stated;
"I say jump straight in with the feathers. Yes, they are sharp, but you learn very quickly to let the weight of the razor do the work for you. If you can get the feather right, then it's plain sailing with the others. A few nicks and cuts early on are nothing to worry about and stand you in good stead. Start with a lesser blade and it's a continual learning process as you step up the level of sharpness". 
Also, member Npsarros stated, "Keep a spreadsheet with every shave [you], have taken, rating each blade as [you], go along". My spread data ratings reads in columns as follows;
Razor Blade / Country / Type - Sharpness? (aggressive, moderate sharpness, mild sharpness, tugging or pulling, ect...), - Closeness of Shave? (DFS, CCS, BBS, ect...) - Smoothness/Roughness of Shave? (moderately smooth, very smooth, very,very smooth, ect...) - Comfort of Shave? (no irratation, slight irratation, touch of burn, itching, ect...) - Overall Rating? (awesome, great, passable or unpleasant), and Compatible with your Razor(s)? (yes or no).
PM me with your e-mail address and I will send you my workable spread sheet example.
The Thread "Wet Shaving Instructions and Tutorials", maybe of great interest to you and is very informative.
Although, you may not be additted yet (I think I'm holding up fairly well...with a few exceptions), because we all suffer (gladly and are doomed perhaps), from this shaving complusion (and other Acquisition Disorders), because at times..."Resistance is futile".

Please don't forget once you get time....please tell us a little about your shaving kit and a little about yourself in the Hall of Fame sub-forum.
