TL;DR: I'm sexually active, experimenting with polyamory, and my dad somewhat seems to slut shame at times. Any advice or support?

I don't really like to talk too much about my sex life, especially with gone wild lurker type strangers messaging me on Reddit, but I'm honestly feeling like I've been indulging in sex a bit too much with one of my current partners. Before the virus hit I was going on tinder quite a bit and then a week into all this shit I just deleted it. Sometimes I just feel like a slut because I feel that classic double standard creeping into the front of my mind. Like, I'm gross, I don't deserve love because I have too much sex to differentiate love and sexual intimacy. It's all getting muddled in my brain. Then the other week my dad, the rare time I sit down and talk with him a little, he ended up explaining how condoms are essentially useless because certain types of STDs or most are at the upper base of the penis. I'm just sitting there kinda not saying anything because...what am I supposed to say to that?  He even asked me the other night while we were watching Hustlers (movie about swindling strippers) if I wanted to be a stripper and why. I replied with "Yeah, maybe one day." He seemed unreasonably upset. It wasn't even the first time he's asked and if he's gonna get visibly distraught about the answer I don't understand why he'd ask. Seeing if I would change my mind? I just want to enjoy sex. I'm starting birth control soon and I recently got blood and urine samples to ensure I'm not putting anyone else at risk.
