I'm a 26-year-old guy, and I'm really concerned about something that's been happening with me. Whenever I think about anything sexual or watch a sexy movie, this clear gel-like liquid comes out of my penis. I'm curious about what exactly this is and how I can stop it. Also, I've noticed that if I get aroused at night or have a sexual dream, I end up ejaculating without realizing it. Could you give me some advice on what's going on?
