Male P spot

Do I have seen a few ladies mention that you can massage the prostrate and it makes it SUPER intense for the guy.. and there is also a way of doing this massage externally.

So I did a bit of research on this external massage, tried it on him and while he said it felt ok it didn’t lead to any “volcano like eruptions” as some ladies have put it 😊

Any tips on how to do this properly? I had the right area and used lube as well but his balls were really getting in the way 😂
