No-strings sex with a guy at work was working well at first but now I’m feeling used

DEAR DEIDRE: NO-STRINGS sex with a guy at work was working well at first but now I’m feeling used.

We were due to meet up last weekend but he had “something else on” and cancelled at the last minute.

I’m 26 and he’s 29. We’ve worked together for two years, becoming close a few months ago after we both ended long-term relationships.

We agreed that we didn’t want anything serious, we just wanted fun.

But it seems very one-sided when it comes to sex.
