Is 24 hours a long time ?
Not so much painful - I've never noticed what I would describe as pain, just a sense of "fullness" and a constant urge, like an itch you can't quite scratch. It can get to the point that it becomes distracting and annoying. It sometimes also results in frequent, sometime persistent, and often inconvenient public erections as the need and arousal stay at a higher pitch, which is a constant reminder of that urge for release. Good thing baggy pants are sort of in style... wish they had been in my high school years!
It's not painful, but there's this instinctive, primal urge to ejaculate. Something hard-wired into me to find a release. I become completely wanton, lustful, horny and sexually evocative after 4-5 days.
Quote by Freddie Mercury
My soul is painted like the wings of butterflies
Fairy tales of yesterday grow and never die
I can fly
The show must go on.
As others have said, the tension builds and builds and I find myself thinking sexual thoughts all the time. If I leave it too long, like a week, Inwill probably ejaculate in my sleep. The first cum after a gap is awesome though.
I will say it is more noticeable, but being painful is not true. However, being teased and worked up, then let down does have an effect.
I actually find it quite erotic to go without cumming for several days. I have found that when I do get off after a few days, the first orgasm is not that intense...however, the second one is very intense and the output is huge. My Mistress enjoys instructing me to refrain for up to a week at a time. I find the built up engird and tension exquisite
Unspeakably unnatural, but not physically painful. It's an emotional pain. I tore something down there once, after having sex with 5 people (2 bi couples, 1 single female) within 2 days. To heal, I could not ejaculate for over a month. I was sad, but not hurting.
I don't really think I notice any particular feeling in my balls, but if I don't cum at least every couple days, unless I'm working out a lot my experience is that my temper gets pretty short and my aggression goes through the roof.
It starts to feel like a stress is building up inside and a frustration that needs to be released
I get a weird tingly feeling if i go over a week. It runs up and down my cock and intensifies everytime I get a boner. And it feels like im about to bust with the slightest touch and i will horny day and night to the point its hard to focus on everyday stuff.
Its definetly weird. When you get hard it also feels like soft and tender, eventhough its rock hard and throbbing. Bright pink and almost reddish head. And since you run a boner very easily there is alot of precum built up which creates a big mess when you finally decides to masturbate.
And oh man when you do masturbate, its very intensified. It will be like running an orgasm from the get go. Obviously you can't run too long. It just gets too much and when you finally cum, I will get that tingly feeling again. Only way more intensified and spreading through my body. The cum will splurt in splashes and shoots further and faster than ever before. A huge heatflush runs though my body followd a sense of relief. Atleast thats what you think. Because i waited so long, one go is not enough. ESpecially now that I am hooked on dopamine flush, i have to cum multiple times till i completely release everything in my balls..
To me, it's more unsattisfied lust. You know that feeling - You wake up and your cock is stiff and erect. I usually tend to take him in my hand and please myself ... I feel like need to. And not having done so for, say, three days, you wouldn't believe how extremely big these balls feel. It feels like being nervous ... But then, when you take him in your hand after such a long time, it feels like a huge relieve. It is most satisfying to feel the first drops run down your shaft. And even more satisfying when you feel how your cock becomes bigger and bigger until you finally how the suffering stops ... That's how it feels to me.
If I haven’t cum for a few days I find I can’t stop thinking about sex and I suddenly start noticing other women more. I feel a tension in my penis as if it’s partly erect. Finally I have to relieve it either with masturbation or full sex.
Yes it is painful. I think the build up of cum and the anticipation of the next shot makes it worse. I do notice my balls do get bigger but i think that is obvious why. My cock gets thicker and gets hard more often when i go without.
If you have friction on your member from wanking or sex or handjob or whatever and don't get to come then the pain can be very real. It actually ruined a date for me last year. I had spent the previous evening with a fwb whose toddler woke up in the middle of you know causing me to have to leave her flat half-cocked. For some reason I didn't do anything about it myself when I got home or the next day. Then in the evening I had a date and after an hour my balls began to feel like they were squashed in a c-clamp. That meant I either had to wrap up the date fast or make my excuses. The first solution didn't work out, maybe because my nut sack was leaving me in agony, so I had to opt for the second one. My date didn't take it particularly well and I never saw her again.
If I go too long, I take care of it myself. By too long, hell, I jerk on days I get sex, so I cum daily, either assisted or alone!
Haven't had to worry since the internet started
