I came out as asexual to my mom and she kept giving me the usual right guy speech, a lot of the time I go out in cosplay so now thinks I am a dyke but shes also trying to set me up with people any advice on getting her to accept my sexual orientation?
You don't need her acceptance or her permission. Be who you are naturally. Quit beating a dead horse. As Cookie stated, it's really no one else's business about your sexual orientation. There's no need to hit her over the head with this; just stop talking about it.
