My ex hated it when I temped. My DF didn't exactly like it but when I explained why I needed to do it he tolerated it. Temping was what alerted me to a possible pregnancy just 18 days into my cycle. I had a short cycle so O'd around day 12 & got a major temp dip at 6DPO & 7DPO so I pretty much knew from then. I could then test nice and early, I think at 10DPO and I got a BFP, so I think it's well worth doing.
