In my opinion not at all
When we started, I told my wife that it was very humiliating and let's stop. She answered me, you can't , because you will always not be able to forget that someone fucked your wife in front of you.
And even after several times I tried to stop and several days passed without sex with my wife she would mention her bull and immediately my cock would stand up and this was proof that you can't stop being a cuckold, she saw it and used her femininity towards me and sometimes she would hand me her panties To smell and ask her to invite him
yes very true, i tried to stop many years ago, to be honest the reason was i was frightened i would lose her to much younger man than me who i could see she had feelings for, she used to see him every weekend, (or thats what i originally thought).
i was working away all week, and would come home knowing she was going to meet him, i would watch her get ready to go out after we had fucked as i had been away all week, having shot my load i would get that angst and didnt always want her to go, of course she wanted to go still, and tease me until i was aroused again, knowing i loved her dressing up in heels,stockings etc, seeing her all dolled up minus knickers bra and short dress/miniskirt
and off she would go
a few weekends later she had been with him again, she arrived home in the early hours and we were having sex, and she told me how she had fucked him every day that week, he had been coming to our place during his lunch break for sex, it turned out this had been going on for some time,, listening to her telling me turned me on but i was also gutted i was only just being told, the next day i asked her about it again and said i wasnt happy about it and told her i didnt want him coming when i was away.
she asked me how she could stop it now and did not agree with me
A row developed and i told her she had to stop seeing him
I went away to work the next week,all i could think of was the thought of him there fucking her against the kitchen sink like she had told me, and how she had said she would be waiting for him in stockings and heels, her words "he told me to be ready for him and wear just those to save time as he had short lunchbreak"
When i got home on the friday evening, late due to traffic she was already dressed to go out, i quizzed her if he had been to the house, and she told me
"Yes he has been every day i cant just turn him away can I? "
She then lifted her dress up to show me her freshly shaven mound and said to me "Do you want me to stay or go and let him have me again tonight"
Needless to say I ended up letting her go that night and for a further 15 months she had him nearly every day of the week at lunchtimes and every weekend
