Just play e6.
how to deal with the f7 weakness in the sicilian

If they just want to give you a piece with Bxf7+, take it. If you're going to play chess, you need to learn to rely on logic not fear. Unless they can follow up with a powerful attack, it's worth it to give up castling for a free piece. It's up tp you to decide whether or not danger is real, not to just get scared by every little threat

my biggest fear is loss of tempo , and that is never good for an aggressive player < i hate comprimising
What is your problem with it? You can play either Nf6 or e6 and there is nothing to fear. Qf3 is a bad move.

You should never even get into that position. People play 2...d6 in the Sicilian after 2.Nf3 because they're either anticipating their pet open Sicilian or a Moscow variation. With the bishop or queen played first there's no reason to delay 2...Nc6.

I am surprised that more white players try to avoid the Sicilian by playing the Moscow variation.
Though black can transpose into a relatively favorable Dragon where he doesn't have to worry about white's lightsquared bishop. Though d5 is weak as usual but then again in highlighting d5's weakness he weakened d4 himself. This obviously only applies to a specific Moscow Variation:

Get going attacking on the queenside or center, before white can get anything against f7.
Beat him to the punch, as it were.
The best defense, is a good offense.

It is the Sicilian, just another variation
It is just another variation, but it gets you out of the main line fairly quickly.

This is good advice for all of chess. Sometimes I struggle with this myself.

One word: ...e6
Seriously though, the f7 square is very very very rarely a weakness in the Sicilian.
If they (white) EVER place a bishop on c4, you play ...e6, end of story, sometimes they'll play f4-f5 trying to open the diagonal, but by that time you've dealt with the bishop by some ...b5 and/or ...Nd7to Nc5xb3 maneuvre.
Lastly, If they follow with some Qf3 type stuff (going for the ol "scholar's still learning the ropes" mate...do whatever you like (you are learning...have fun!) but if you lose, you should study around 100 of Morphy's games (http://www.chessgames.com/perl/ezsearch.pl?search=Morphy) until the standard tactical patterns have been assimilated...Without them any "rules for the sicilian" are not helpful anyway.
Thats my opinion :)
P.S I'm not trying to sound condascending or haughty or whatever...I just have a blunt "NO B.S" approach to chess instruction.
Hope its helpful :)
P.P.S Those beers I just finished werent bad!
many times when i play the sicilian , i get very scared as the light square bishop gets trained on the f7 square so early on the game with in my head ( and few experiences where in the rossilimo variation i play d6 and though i have given my king an escape route , i may have to forfit my right to castle and get kicked arund either by bishop sacrifice on the square followed by a queen attack with the help of a knight or just in the classic queen and bishop battery and the scholar mate , to my relief like 99 percent dpnt take on the square if they get out their lsb early but the idea still makes me have doubts about playing the sicilian
