Okay I'm going to answer this after all. Yes, they feel different.
For a lot of women, it's really hard to have a vaginal orgasm. A lot of women don't like either types of orgasms because it feels either too intense physically or intimate, it can bring back post traumatic feelings for some, not gonna get into why but I'm sure some of you can imagine.
I've only had vaginal orgasms a few times, with people I was really in love with and felt really safe with. That connection to me is impossible to have with a client, even if I'm really good at developing relationships with those I see on a regular basis, and new encounters are often filled with joy.
I also fully understand why escorts don't want to orgasm with their clients, it's a deeply intimate thing.. With this line of work, I already have to give almost all of myself, particularly intimately. The only things I still refuse doing is anal, bareback sex and really rough play. Of course, that is my personal choice, but I recognize that if I didn't do sacrifices for this job and give so much of myself, I wouldn't be so popular. I'm happy to do so, but there's a limit.
Sometimes clients want to watch me climax, I've been able to do it with certain people in the past particularly using a vibrator but it's become harder and harder precisely because the more I move forward in this industry, the more is asked of me and the more I feel exposed in many ways. So I want to keep something to myself, and I think it's possible I might stop doing that eventually with new clients. Something can feel good physically but not feel good emotionally. I just want to keep something to myself.. I also understand personally why some escorts don't want to do DFK, for a similar reason.
