I've got exciting news. I took a girl I liked out to a date on the beach!
Why did you take her to the beach?
Because I'm a naughty boy and I wanted to see her naked.
It's good to go out on a date with a girl that you like, but taking her to the beach just so you can see her naked is gross. If you like someone, take them out on a date that you can both enjoy, don't take them out somewhere that just benefits you. If she finds out that you just wanted to see her naked, she's likely to lose interest in you.
I just want to show her how fun I am.
The main thing is that you want to spend time with her and that is healthy and a good way to make a relationship strong.
