I guess the men are stressed. Maybe dun tell them the motive of sex. Just crawl on them n seduce them to bed u.
I do that at times, I have to arouse my husband to get him into the mood. He's got a thinking and stressful head, I get scared that the sperm quality might not be good when the man is stressed up, just like the woman.
So it's important both of u r enjoying the sex moment together n not stressing it out.......
Have a lovely evening with light music, warm shower for the lady n cool shower for the man. Man taking warm shower must wait atleast 30 mins to an hour to cool the heat, so that the sperm is good. I read this somewhere...
