Why does he get erections?

Yeah, you should be happy that he’s aroused. It shows that he’s not “going through the motions”

He gets a boner because be fancies you and wants to shag you.if your Ready to take it further when he gets a boner put your hand down his pants and jerk him off until he cums your thumb and first two fingers hold around his erect cock and rub up and down watch his face to see how firm to hold his cock if he looks in pain then slow down and don’t grip a’s hard ( most men enjoy quite firm and slow up and down) do this until he cries out and shoots his load ( his cock will get really stiff in your hand and start to pulsate as he cums, he will probably groan or scream out as he cums, he may swear if he is that sort of guy something like oh god,oh Jesus, oh fuck yes). Once you have given him a hand job he won’t be shy about his hardon with you anymore then after a few times of regular hand jobs he will want blowjobs ( when you put his cock in your mouth and down your throat and lick and suck him off until he cums in your mouth). Then after a few blowjobs he will want full sex too insert his hard cock into your pussy and thrust into you in and out until he ( and hopefully you too) cums inside you this is when his warm semen pumps out of his hard cock and into your pussy whilst its inside your vagina ( hopfully but not likely your first time most women don’t orgasm the first time they have intercourse, some never orgasm during intercourse or throufh penetration from the guys cock on its own) making you orgasm.

If you can tell he has the boner, you NEED to make the move on him, the guy want take it cause it would feel awquard for him.

And yes us guys can get very turned on and earn boners from women being with us.

You Women just have NO IDEA how you make us men feel, like really, take an advantage of a situation if you get a chance, the guy will love it.
