She's been mentioned before on other threads but there used to be a girl who worked at Preston VIP and went by the name of Sandy

Apparently she was voted as being the best oral provider in the NW, think it must have been on some now defunct other punting site
I could never cum from oral, it felt good but for some reason I just couldn't quite get over the line until one day I punted her and her oral was just mind blowing

I ended up spunking in her mouth and discovered that the orgasm I get from oral is 100 times better than from penetrative sex, I can only assume that it's because i'm not in control of things whereas in mish or doggy i'm controlling the thrusting and sensation etc

Anyway since that day i've not had an issue cumming from oral sex so i'm thinking it must have partly been a psychological thing

All sorted out by "Nurse Sandy", glad I went private
