repressed whore is still repressed [MF]

Some background and description because it might matter to you:
I’m a 26F, 1.65m, 57kg.
Ren (fake name) is a 28M, around 1.8m.
we’re both physically fit people who workout.

The first time I felt like Ren might be up to something was when he walked over to my desk to discuss some work stuff. He knelt beside me and positioned himself beyond what is a normally comfortable and acceptable maximum distance to keep from a co-worker of another gender, his knees grazing my thighs, and launched into a discussion.

I tried to follow whatever he was saying while trying to subdue the embarrassing sensation of keenly feeling a small part of his body on mine, while trying to silence dozens of questions about his abnormal behaviour. they threatened to fill my mind entirely and block out the work discussion.
1. There was no need for him to come so close to talk to me – it wasn’t a confidential discussion and there weren’t people around us that we’d disturb from discussing it at normal volume and physical distance;
2. We sit directly opposite each other, our desks separated by a short cubicle wall. honestly, he could have just stood up to talk to me.
3. Did he even notice that he was being abnormally close and that I was shy about it from my obvious blush that’s making my ears and cheeks boil right now?
