That is a no-no that is major and dudes understand this. For the sex if you have recently just had a great date, or great sex and the guy hasn’t texted you back after 2 days, assume he was only in it. Many dudes will text a day later following sex and when they don’t, then don’t beat yourself up about it – ponder over it a course and good riddance! I am aware it’s too an easy task to state riddance that is good. Often this component can hurt really.
