Guys, you are all doing it wrong. Even you, OP. The only answer worth giving is "NOT FUCKING ENOUGH"
At last count, if you include my dad's guitars (I do, because I play them more than he does and I live over 9,000 miles away from him/them), the number was 9. Not counting my dad's guitars, I've got 6.
Edit for lists. My six:
1. Gibson Faded SG Special, cherry
2. Johnson Stratoclone (personally autographed by Bo Diddley, it is my pride and joy), metallic silver
3. Squier Bullet (hardtail), spraypainted and stickered
4. 1953 Kay acoustic, natural finish on a Sitka spruce flat top
5. Arbor copy of a Les Paul, cherry burst
6. Some shitty PRS clone that my stepmom's brother built (poorly) and gave (unloaded) to me as a present
My dad's three:
7. 1937 Kay acoustic (my favourite acoustic guitar of all time), battered to hell with a Sitka spruce top and natural finish
8. 1973 Fender acoustic, not quite sure what model
9. 1983 Epiphone acoustic, again not sure which model
