I've searched old threads for this but nothing came up. A few months back our 3y/o male cat began to get, erm, amorous with both DH and me (mostly me though) also with clothes we have worn.
It's not easy to discourage him, he is very determined. We pick him up, placing him on the floor with a firm "NO", but he'll keep trying for hours at an end. He was neutered at 6 months, and never shown this type of behaviour before. He's begun showing interest in friends that visit 
Does anybody else have a cat who behaves in such a way?
