You: I have trauma I am working very hard to deal with. I just need you to be patient and not pressurise me.
Him: But how lonnggggg and whyyyy -stamps foot on ground-
You're dating a toddler who can't seem to think or feel beyond his own needs. No respectful person worthy of your love will make you feel pressurised into sex. They wouldn't care about waiting a few weeks as long as you were okay.
I mean, it's fair of him to not want a dead bedroom and I wish him the best of luck finding a girlfriend who willbe at his beck and call and in the mood 24/7. If 'dead bedroom' is what comes to mind after a short period of having some issues, then you might as well chalk it up to sexual incompatibility and him being a doof about it.
