Scott, Catherine is only 19 and is justing wanting to have fun with her school friends. But she is becoming very comfortable in her steady relationship with Kyle and before very long, Kyle will run his hand under clothes while he is kissing her. She will not be able to say, "no" to the wonderful sensations flooding her body, and will allow Kyle to take her virginity with a condom on. She will confess to you and you will tell her you don't mind what has happened.
You and Catherine love each other, but Catherine has little experience and it is natural for her body to want to try sex and kissing with a number of guys before wanting to get married. You have already felt the pleasures of being a cuckold, and when Catherine tells you that Kyle went all the way, your penis will go so hard that you will have to rub it and release your sperm.
You should be going out with other girls to match up with Catherine going out with other guys. You can still love each other, but you both need to sow your "wild oats" and get the "sexual itch" out of your loins, so that on your wedding day you will be able to commit exclusively to your bride and her to her husband.
Shy girls get "turned on hard" when their boyfriend gains enough confidence to maximise the foreplay. Kyle will take her over the edge when he is ready, and she will fall head-over-heels in love with him and his cock.
She will still care about you but on a different level to Kyle. A girl never forgets the guy she loses her virginity to. Forever, he has the key to her door and heart, unless he does something stupid to annoy her.
IN the long run, Kyle will see you as surplus baggage, unless you discuss with Catherine your desire to be formalise a cuckold agreement which lets her have as many lovers as she likes on her own timetable.
To be a proper cucky, you need to be married for several years before your wife begiins to "wear the pants" in the family and boss you around.
At 20 you should be having fun instead of being caught in a "does she love me, is she cucking me, is she drifting to other guys, is she secretly fucking them?"
I will enjoy reading anything you write on this thread, whether you decide to allow yourself to be cucked or not.
Remember that Catherine is new at sex, and it is not fair to want to know every move she makes. She needs room to grow emotionally and to try the various sexual positions that Kyle (and others) will teach her. You will make it harder to enjoy herself sexually if you are like a Policeman checking up on her all the time.
True love means she can experiment and not tell you everything as it is the only way she can find out what she likes doing.
You will have to choose the time/place to tell her that your cock goes stiff everytime she talks about what she is doing with Kyle. Not all girls can understand that a guy who (says he loves her) would get turned on at the thought she is getting welll fucked by other guys. But that is not to say that Catherine could not learn the right things to say to give you the frequent erections your inner mind seems to be lusting for.
None of us want to see you hurt at such a young age. Matt Crowe was 25 and his girlfriend, Tina just 20. Matt had a very hot time with lots of girls for several years, and has encouraged Tina to fuck like a rabbit to catch up with him. Only problem is that Tina is now addicted to opening her legs for lots of strangers, and she will continue to need extra lovers once Matt and her get married. Most of her lovers are black and she easily falls in love with each one.
Kyle will become Catherine's white bull and if she becomes preggie accidentally, you will have to decide how strong your love for her is. A real cuck would say, "no problem, I will raise the child as though it came from my own seed".
It would be so much easier if you could wait until you got married before doing this cucky thing. But good luck in whatever you decide to do.
