Wow, how time's have changed
In the words of my daughter, you really are "Deeping" this, please don't give it a second thought. Jeeze. If he didn't like it he would move your hand away and say no - simple.
Seriously, you are making out with a lad and have a quick feel, he will think Christmas has come early. I appreciate that poster @Catin comments "lets not have double standards in 2022" but come on it really is NOT the same thing. Teenage lads in general are up for anything, a girl snogging their face off whilst giving them a quick tug, he wont be complaining i can tell you.
I remember when i was younger, i was at a school disco and it was fairly dark with the lights flashing, my mate Phil was near the corner of the room in a deep kiss with a girl he had just met and she was full on, tossing him off at the same time. Suddenly the music stopped and the lights came on for the end of the disco and there he was in full glory. We had a right laugh i can tell you. He laughs about it now, totally embarrassing, he wasn't complaining or going for counselling, you just move on, all part of the learning curve. Guys just do not think the same as girls do, its how it is.
You go and survey100 teenage guys in your local pub and ask them if a girl was in a passionate kiss with you and tried to feel your todger at the same time would you be complaining? you wouldn't find one guy that would say yes.
Now you can call that a double standard and yes, it probably is, but that's life, guys do not think the same as girls do as i say, we are different.
I suggest you read the book, Men Are from Mars, Women Are from Venus by John Gray you will find it enlightening. Equality is all fine and a good thing but it just doesn't lend itself to EVERY situation. Men and women are essentially different thinking creatures that coexist together, one is not better than the other (equality) but we are different, some might not like this fact but its fundamentally how it is and at times we should recognise that and dare i say it champion it.
Honestly, things were much simpler when i was a teenager i can tell you...
