Would you kiss someone of the opposite gender/sex, of what you are attracted to, for (a) Science (b) Art (c) a Favor (d) a Dare? If you are attracted to all: N/A.
Only fair that I answer it as well. (a) Yes (b) Yes (c) Yes (d) No. Why not for a dare? I don't think it's daring. There's no risk, really. It'd have to be someone specific, and someone I very much dislike and/or is gross and slobbish for a dare.
