Masturbating with partner

Who else masturbates while having sex? My ex would beg me to and turned on all the lights to make sure he could see and he would jerk off at the same time. (It was so hot to see him do it especially knowing he was doing it to me) The person I am with now I was scared at first to do it but one time I just started fingering myself during and it turned him on so much and it’s now his biggest turn on. He doesn’t jerk off but he does play with my nipples while I finger myself.It literally feels so good and I work myself up and have him finish me with sex so my orgasm is so intense!!!
