WHAT DO I DO PARENTS STALKED MY FIRST DATE AT 23.. NOW IM SCARED IT LEFT A BAD TASTE IN MY DATES MOUTH

So I’m 23 F……. today I had my first date.. I am very very close to my dad..he knew about me meeting this guy and my meet up with him, I even talked to him about it….he had his talk with me about me not going inside his house & driving to wherever we were going….. Fast forward … the date was at a beach.. i get to the beach we see each other, then we hug. we talked for a while asking each other questions .. I kind of brought up the fact I’ve never kissed a boy before, through text so he had brought it up in person.. no biggie.. so we began to walk around the campus (the beach was near his campus).. as I’m walking I see my dad and stepmoms car riding in the parking lot I laughed to myself because I figured they just wanted to see how he looked.. nahh.. THEY PARKEDDD to where they could see us … so as we are walking they would like inch up in the parking lot to try to see.. at this moment I’m pissed because I know a kiss is going to happen becuse I feel it.. so we sit down in this common area.. talking, it was soooo nice, private(😐), then he started rubbing my leg.. what do I see .. the car parked there sitting like they were watching damn fireworks.. so I hop up.. and poor guy was like are you okay whats wrong what’s wrong.. and I’m just tweaking like.. “I’m fine let me walk you to your car, I’m just really really shy” so we get to this corner.. he stops me and grabs my face and says come here.. I COULDN’T EVEN ENJOY IT BECAUSE ONE EYE WAS CLOSED ONE EYE WAS SPOTTING FOR THE CAR.. I was sooooo pissed.. I had to pull away.. look over I saw the car again he wanted to kiss again but I said no .. he can tell something was off.. he walked me to my car and in the parking lot was my car, 4 other cars, and their car just parked staring (their trying not to be noticeable in an empty damn parking lot) .. I then told him that my “cousins”were in that car and I didn’t want to kiss again because of it.. so we hugged and I got in my car he walked off .. THEN THEY PULLED OFF. my stepmom texted me and asked was everything okay.. YOU SAW EVERY DAMN THING.. (except for the kiss because it was in a corner)… when my dad called me after I was venting to my best friend about it .. his excuse was “just wait until you have kids” .. I literally was short talking him and he got upset..

TEXT MESSAGE

ME: Go Home (7:14 Pm)
ME: Wow this is so crazy you don’t even give me privacy. ((7:20 Pm)
he doesn’t respond…. When I get in my car and the guy walks away.. my dad pulls off and text …
Dad: I trust him now I’m good.

I haven’t talked to my date about it and I don’t know how I should bring it up or what I should say.. what do I do?
