Hey There,
Pretty much, bending notes is perfected by practise, if your fingers aren't strong enough, give them time to build up.
In a way, it's a little like building the muscles in your arms up so it does take a little time to get used to.
The only other thing I can suggest, if you are using a thick string gauge, try some thinner strings as these tend to bend easier. Gauge 9's are probably better as you don't lose the warmth and feeling of the guitar tone, the most common are probably 10's.
