Hi Claire, my advice is to take time to explore what you're really feeling for your boyfriend, your best friend. Don't feel you have to decide anything right now..try not to put any time limits on your search for your personal discovery. It took me nearly 40 years to find out enough about myself to know I am a lesbian.You'll be a happier person if you take time to listen to your heart & balance that with what your head is saying & ignore all the stereotypes that society is screaming at you! Wishing you all the best, Pooks.
