YES it is completely normal my bf always gets a boner wen we mke out or even just wen I'm holding his hand sometimes...yea haha don't be worried he can't control it
Sure, that just goes to show you that you are doing it right.
I'm a guy. I remember one specific time when all that happened was a girl told me I was hot. I got a boner. A boner doesn't even have to mean that you are sexually excited in my opinion. It's just when you get this feeling just being with or thinking about girls.
Yeah it's completely normal.. It's actually a good sign.
