Self inserting as the loli has been popular since the start. A bunch of interviews and essays in lolicon magazines from the eighties talk about it.
Although I'd say if you aren't attracted to the loli herself you aren't one. I'm pretty sure most people who like gender bender and crossdressing and self insert into the opposite sex do it cause they want to be someone they themselves find attractive, and so would want to self insert into the loli partly because they are lolicons, but that last sentence seems to imply you're not even attracted to them, so I'd say >>24062 is probably right and you're just a gigantic faggot.
