For me, I think it is just our own physical hormonal fluctuations who are making the differences over time.
I can't explain why a time, I did not like generally a certain touch, and after few years like it, to dislike it again few years after, by example.
Of course, what you mentioned is playing a role, but orgasms are also changing while masturbating alone. And I am not talking about how aroused you could be, just ordinary day to day masturbation. :smile:
