circumcision n prone masturbation worries...

hi
i was suffering from phimosis and got circumcision done recently (2 weeks)....
i was going thru all the forums here n there which says circumcised men reduce masturbation coz of reduction in senstivity..
also i used to masturbate in prone position earlier and never masturbated normally coz it never worked for some reason even after trying for 20mins at length, in prone i ejaculate sometimes even under 5 mins....

now i read that prone is highly discouraged n after cc(circumcision), i dont think it stands a chance...

so is normal masturb. with cc easy to achieve or will i have to struggle??
i read about using lubricants, so dat means always i have to use lubes for masturb. ?? and how long should i wait before trying it, i mean got cc done 2 weeks back? i am really anxious n worried about trying normal with cc...
and got a date coming with my long distant gf in 3 weeks, should i try for some action dat time, more importantly, will i b able too..

plz help, really distressed.....

thanks
