Reading @Abby82 's initial message, where she writes boys want to "go forward too fast" and im not ready to that
, I interpreted that more as a concern not for strangers physically assaulting her but rather guys she knows trying to persuade her to do things with them she doesn't currently feel comfortable. As @Megan suggests, self confidence and assertiveness as well as an ability to communicate boundaries well would probably be more valuable than self-defense classes in those situations (although perhaps self-defense classes could also boost ones self-confidence :-)
