This whole process is like climbing steps. I was just like you too. First was getting my head in order. Did a lot of reading and discovering sites with information. Then talked to some guys for their opinions. Since I was not very outgoing at the time, to find sex I went to a bathhouse. It was like a school for sex. Took my time and each time I went, I tried something new. At first I was a top. Then I became more bottom. I always played safe. Slowly I got into barebacking. The feel, top or bottom, is so much better. Leaving a load in another guy's hole was hot. Soon I was getting fucked raw and feeling loads of cum leaking out my hole was amazing. Became a total bottom then taking many loads. As time went on I moved to where I am now. I am vers. Like it both ways and with many types of guys. I am very open, but I know what I like and what I won't do. The key, for me at least, is to let you guide you. You will know when to climb the next step. When to rest or maybe take two at once. You may stop and spend time on a landing. The point is to take your time. Listen to your inner voice and follow it. Don't let someone else control you. You climb the stairs as you are comfortable doing so. For me it has been a fun, exciting climb. I have had amazing, fun times. And there are more fun times to come. I am so glad I let myself climb those steps.
Have fun!
