Any SQL within a pl/sql block is recursive SQL (user recursive, rather than SYS recursive) so this time could simply be the cost of running your application code.
Unfortunately the tkprof output doesn't quote the recursive depth of the SQL - however if you identify possible suspects, you can check back in the raw trace file for lines like: PARSING IN CURSOR #N there will be a bit in the line like dep=n If n is not zero, then this is a 'recursive' cursor.
