Hello 18f from Yorkshire! First, you have to know everything you are going through is perfectly normal. Telling a boyfriend about that can be very hard but like Staci said in her reply, If he loves you, he'll understand. It might take him a while to adjust and you might go through some hard times but things will get much better and the burden will be off. NEVER be ashamed of who you are... Just let it be what it is
You're not alone! There are many ppl behind you!!
