Very interesting question to say the least for only recently have I started to give my age regression any serious thought. I do a little bit of fantasy writing (for my own pleasure at the moment) of which I have found that I seem to like the age of being 10 or 11. But I have in the past few months enjoyed a little bit of role playing of which I was to be a 6/7 year old boy. I have to admit that I rather liked it and our role playing chat turned out to be very rewarding, to say the least.
But what surprised me, as role playing is a bit new to me, was in how in a very recent chat I was asked if I would mind being a little boy of 3 or 4. I was taken back with that but then I realized that I have had very lovely thoughts about being a little one of that age, sort of going through the transition of needing to wear pull ups but then wanting that big boy feeling of wearing proper little undies, so I chose being 3. Without getting into details, it was a most rewarding and lovely experience of role playing.
So in answer to the question, I would have to say that I found to most comfortable with be a little one of 3, and still enjoy being that 10 or 11 year feminine feeling boy who is exploring things.
Ohhhh as a side note, it became very clear in a short period of time that I will not tolerate any suggestive forms of abusive nature or qualities from any role playing partner. I have a rather strong gentle feminine side to me and as such role playing must be of that quality in order to be enjoyed to its fullest heights.:smile:
