Man faking it?

[Lovemusic33]

Not sure why I'm writing this, slightly embarrassed writing here

My dp doesn't always finish when we make love, sometimes this makes me quite frustrated and makes me feel like I must be rubbish in bed, it also frustrates him but he assures me that it's not me and it's a problem he has always had.

Last week he worked away for a couple nights and when he returned we obviously wanted to make up for the time we were apart but again I was disappointed, he got quite frustrated and we ended up arguing a little. Last night ( after a break from trying ) we tried again, he told me he had finished but I didn't feel him cum ( I usually do ), I kind of went along with it but ( sorry if TMI ) there was no evidence that he had cum when I got up to go to the loo. I am pretty sure he faked it and now I feel pretty upset about it . I haven't said anything to him, should I say something?

He often says he feels like he has cum but he hasn't actually ejaculated so maybe this is what happened but surely he would have known?

Some anti-depressants suppress ejaculation.

Name changed.
This maybe a bit TMI. I've been with OH for over a year. I have never seen him orgasm from a hand job or oral and when he supposedly orgasms from PIV I've never felt wet from it, you know when you need to get some tissues and mop up a bit
He says he does orgasm but I don't believe it. The other day I asked him outright, have you faked it, and he said no but he is a private person. I said he needs to communicate me if he isn't but he just clammed up.
I really don't think he is orgasming. With every other man I've slept with, it's obvious but with him it's not. I'm on the pill so we don't use condoms so I can't see what's in them for 'evidence'
I do not orgasm through PIV, I need clitoral stimulation and I have faked it before, so i can understand if he fakes it, but every time??
