You have my sympathy mate but you like it really! Your general question about will it get easier is like asking how long is a piece of string. I've read quite a few posts on this and other sites, some where the guy's say it DOES get easier and others that say it DOESN'T. The answer is only in YOUR hands and mind.
Chastity actually made ME even hornier than I ever was (that's an understatement). Mornings are particularly difficult and I usually wake up somewhere between 3 and 4 am trying to burst out of my cage. As soon as it wakes me I just ache for relief and even after going to the toilet and having an icy cold wash, my brain is switched onto wanting rampant sex. My only half solution is to cuddle and kiss my Princess and when she wakes a little she is very understanding (although unsympathetic) of my frustration and cuddles me in and strokes my belly. Although at first it makes me much worse and I start gyrating against her leg for a while, her attention eventually makes me feel a bit better. She sarcastically say's things like "Oh HE'S being a naughty boy this morning isn't he? SHAME!". If I don't calm down quickly enough she'll say "That's enough! Now calm down and get back to sleep!". For me, that's when the "penny drops" and my brain starts to accept the situation and my attempted erection subsides a little, still leaving that frustrating fullness and ache in my belly.
Does it get any better? Well all I can say is, for me, I've not been allowed an proper orgasm since October 2013 and I've not even been allowed to touch myself un-caged since then either. I have to be very thorough cleaning myself with the cage in place and my Princess removes the cage twice a week and washes my bits in the shower when she also teases and brings me to the edge several times before she then dries me off, creams me and replaces the cage. All I can look forward to is a very cruel milking every 4 to 6 weeks and believe me I really DO look forward to it just to feel those spasms at the edge over and over again until my body can't hold it any more and I simply leak some of the fluids

. It would sound sad to most people not into chastity but that's what we crave - the attention of our loving partner. The answer is .... "No! If anything the frustration gets worse!"
As for when
I'll next be allowed an orgasm, Princess mentioned in passing conversation just the other day "Not THIS year anyway!". When we started the lifestyle she didn't like denying me but it wasn't long until she found out how much sexual power she felt and how much she really enjoyed having fun out of seeing my frustration.
Enjoy it, you'll find ways to deal with your frustration that keeps you in that delightful zone virtually 24/7.
It's an epic journey and we all do it differently. Good luck my friend.

All I want is to keep my Princess happy. I never wish to offend and only turn my back on those who wish to offend me. I have no bias of religion, race, politics or sexuality. I only wish health, wealth and happiness on the entire human race.
