Is it normal to jerk off reg people’s instagram pics?

I actually do this sometimes. Its usually someone i know. Like one of my wife s friends, I fantasize about them and jerk off to the face pics. But honestly i have to be really horny to do this. But yes i have done it a few times. Most times i have some memory of seeing them in a sexual way. Like one time it was my wife’s friend who stayed with us for a while and i saw her coming out of the shower a few times. Or my mother in law. She would come over and barge in on my when i was in the shower. Sometimes i would just come out of the show and get dry all while she is talking to me.

Regular photos don't show off the good parts. A good porn does. XD

Well it's good that I am not on insta but I am not sure how would I feel if a girl masturbates while watching my pic... Idk whether to feel happy about it or disgusted so can't tell you that its normal or not

No.
