My daughter (15) is dating a transgender boy (15). How do I talk to her about safe sex?

My daughter (15) is dating a transgender boy (15). How do I talk to her about safe sex? I am totally lost here. Of course because they are so young I’m hoping they wait, but if they don’t, how do I discuss safe sex with my daughter in her relationship with a transgender boy? I know pregnancy is off the table but I’m not sure what I should be addressing with her. via /r/Parenting https://ift.tt/2YsaATD
