FWIW, based on my experienece and that of my close friends,I don't think grade-skipping is really the issue with HG/PG girls wanting to date older guys. I think wanting to date people who can get your jokes and who have the same interests and level of emotional maturity is the issue. If she has the opportunity to hang out with guys her own age who meet those criteria, then she'll probably be interested in dating them. Gifted summer programs like THINK or TIP might help get those relationships established.
