need advice

I need some advice. This weekend I was at a concert festival outdoor on the beach. Let's just say the people around me were very attractive just to keep it PG. I ended up masturbating when I wasn't at the concert. So my question is how can I avoid this going forward? My second problem is I have been reading this series. Please note what I am about to tell you I didn't know they had certain scenes in the book. If doesn't say on the book of course. Anyway the book has some pretty risky scenes that one can only imagine. Again keeping it PG. I bought these books on the nook app and it's a great series. It's about 6 books long. How can I avoid masturbating or thinking of this stuff when it's in books. I mean I read books that have some some of this stuff but this goes into detail. Where other books may just glance over it briefly with just one word. My 3rd question is my dad been kind of annoying lately. I am still in college and I am working on my business. I told my dad that I have been doing some website testing to help make ends meet. I have been running my business for 7 years I have made quite a bit of money. But since the pandemic it's been slow. So my dad said to me that's not going to pay your rent when you are out in your own. You need to start thinking about your future. Let me tell you right now I think about my future all the time and it's overwhelming me. If I have to I will get a job to help support me and my business. But I feel like whatever I do my dad always lecturing me and nothing is ever good enough. When my brother was in college he didn't say all this to him. Don't get me wrong I love my dad and I know he just trying to get me prepared. But lately people getting laid off from their jobs there is really no job security anymore. Just in my opinion or from what I read in my news reader app. So my 3rd question is what can I do to about my dad's thoughts and opinions? Sorry for all the questions and wordy questions.
