we usually say ‘please’ when asking for something,
or as a polite (nice) way of saying yes to an offer:

‘Please can I watch some TV?’
‘Can I please go out to play?’
‘May I please leave the room?’
‘Could I please have some ice-cream.’
‘Would you like some ice-cream?’
‘Oh, yes please!’
‘Do you want something to eat?’
‘Yes, I would please!’
‘Oh please, that would be great!’

The word please can be used to show satisfaction and pleasure.

‘I’m pleased with my new car.’
‘This job pleases me.’
‘Your music gives me pleasure.’
‘I’m very pleased to meet you.’
From those few examples you can see that
‘please’ and ‘pleasure’ are closely related in origin
but are sometimes used in completely different ways.

If something makes you pleased,
you can say that you feel …
uplifted
perked
gladden
overjoyed
over the moon
