Interesting. If I am reading your post correctly, then I also might have committed a Mind Projection Fallacy when I read your post, projecting lack of assumption when there was some.

it was cheeky of me to assume I might know more about how he can self-modify than he does - in one of my first posts.

From your post I thought you were expressing that at one point you reacted to gay affection similar to what he described and similarly thought that you could not self modify. You now know that you can so it makes sense to spread the news and method to someone who thinks they can not(who would probably want to if they could) and might be in a similar position you once were and might apply the same solution. Of course maybe Yvain is not in a similar situation and your solution would not apply. You might know more, but there is a better chance that the two experiences do no overlap.

My response comes from the use of "can't self-modify" rather then "can't self-modify due to lack of time/resources," "my continuing efforts have not yet borne fruit," "I have tried all of my ideas and I am seek new ones," "other projects consume my time and it is not currently worthwhile to pursue," and etc. I have seen many people put road blocks in front of themselves by saying "can't" which often reenforces the belief in "can't" rather then staying cognizant of the conditions that make something unworthy of investment.

It may be cheeky to assume that you know weather this particular self modification is worth the resource use to Yvain, but it is not cheeky ask for more details(which are only for Yvain to share at his discretion) or offer personal experiences that Yvain may glen some insight or solution from.
