Agyemang has become a big favourite at Fratton Park since joining in January and was given a standing ovation for his starring role in Saturday's 3-0 win over Sheffield United.
The 32-year-old, who will be a free agent in the summer, told The News: "I'm trying not to give too much away. But we'll see what happens.
"There are positive noises and I love being here.
"The fans have been amazing to me and made me feel welcome. I'm happy at the moment.
"It's good to be appreciated. That standing ovation was brilliant.
"It's a good feeling to come off the pitch and have 18,000 fans cheering my name."
