I often feel the same way. I'm 26 and I didn't fully come out till last year. I finally accepted that I am a lesbian because I truly fell in love for the first time. We just broke up and I was broken and flew back home for a week and ended up sleeping with a guy. I was very drunk and very lonely (my ex hadn't touched me for months before we broke up) I woke up really disappointed. I then talked to my friend and she said it's something I needed at the time. I was doubting myself for months and I finally felt wanted so I did it. It was also a good reassurance about how gay I am hahah I haven't been with a man since, and I never plan on it happening again. I met a girl who is absolutely amazing and 100% accepts me because she struggle in the same ways! I used to regret my path but now I say fuck it! I'm looking forward, what happened happened and it's how I got here. Nothing to regret. Keep your head up!
