Obviously you can do. There are no such rules that males can't do but some institute can impose some restrictions for boys but there are many institutes which offers Nursing degree for Male candidates. Now you didn't mentioned your state, I can't say properly. But in general some of the colleges in West-Bengal:

1. Calcutta Institute of Nursing and Paramedical Science, Kolkata.

2. IAS Academy, Kolkata.

3. Charnock School of Nursing, Kolkata.

4. (IAS Academy), Kolkata.

5. Aliah University -City Campus (Park Circus), Kolkata.

6. Peerless College of Nursing, Kolkata.

I hope this helps. All the very best for your future endeavors!
