Sildenafil contraindications

You got my attention, lad. I am now looking for remedies other than sildenafil and tadalafil. 5/5

At the risk of also being called a lair, my husband developed a similar reaction with a drug called sildenafil. The first time he tried it, it took about 3 to 4 hours to loose his erection.

C'mon, Doc...Viagra ( Sildenafil ) was developed to lower blood pressure and help prevent heart attacks! It was only discovered later that it has the benificial side effects that have made it famous today. His wife probably helped prevent him having a coronary even earlier than he did.
Great story though....

Like you I’ve found it needs no more that a quarter of a Sildenafil tablet to give me an erection as steel hard as when I was 16, and which stays up ready for another go even after I’ve jerked one off! Read my “Viagra Powered” for an interesting side effect of Viagra I discovered.

A delightful tale, well written - and a nice 'twist' on the old 'snowbound at Christmas' theme! I gave this one a solid '5'.
To the commenter (Sex4lf57?) who said that Viagra doesn't work this way, I'll toss at least a cautionary comment or two.
Viagra is derived from a medication (sildenafil citrate) that was originally designed for cardiac patients. To prevent stress on the heart (that can cause a heart attack), the chemical causes the capillaries in the body to open as wide as possible, allowing the blood to flow freely with less pressure being applied by the heart.
As such, it also opens the capillaries in the corpus cavernosum of the penis, which leads to an erection. Now, there's a 'valve' that limits blood flow to the penis, so as to allow urinary function, without urine being able to seep into the passages where sperm travels. When a guy urinates, the semen passages are cut off - and when he is erect, the urinary tract is cut off, because the urethra (tube in the penis) does double duty.
When there is sufficient erotic stimulus to cause that 'valve' to switch the seminal tract to 'open', it also opens the sphincters that control blood flow to the penis, so that the capillaries can inflate completely.
During the years (nearly 60) that sildenafil citrate has been in use in cardiac patients (under another drug-name), it was noticed that when a patient was taking the drug, he was more susceptible (at an older age) to more-solid erections. Gradually, the doctors prescribing the drug got 'field reports' from their patients, and forwarded them to the company that makes the drug. Its use as an ED drug is secondary, and took a long time for FDA approval to market such a drug to non-cardiac patients.
When the person taking the drug is in their late teens or early 20's, and has a quite healthy circulatory system - and is around a near-continual erotic stimulus, as is the main character in this story - the effect CAN be a near-perpetual erection. Even the attempts to diminish it by masturbation won't necessarily cause it to go down, when there is a hotly-desired woman present and making subtle erotic comments to the male.

There needs to be a logical explanation for why sister stops taking pill out of the blue (and also apparently Mom?) Shouldn’t be as mundane as she and Scott are trying for a baby. Maybe have Rachel explain to Jacob during one of their subsequent fucks, that for some reason (in addition to the growth of her breasts) when she took her BC pills after the first time he came in her, it caused her nausea and pain in both her vagina and breasts. She saw her gyno who is baffled as to the cause (obviously no mention is said that she fucked her bro and took his hormone laced jizz inside her). All the gyno recommended was to stop taking the pill until her “hormones” settle down. Karen as well had suspected as much from her own side-effects experienced after she ingested Jacob’s cum and had stopped her birth control a while ago—which is why she’s been leery of Jacob cumming inside her til now. Perhaps have DA Melissa Turner get confirmation of all these findings from the doctor in jail. He can state that his previous specimens had similar effects on their partners and contraindications with her birth control. Also he should warn that condoms also don’t interact well with the WICKTropin as the hormones secreted into the semen can become toxic with the latex. Prolonged and vigorous sex leading to ejaculation could result in a busted condom. Also the combination of WICKTropin semen, latex and BC pills will definitely cause pain in a woman, in addition to breast growth, added body curviture and fecundity. All these warnings and advisories lead to at first more careful sex between Jacob and his Mom/sister/Ms. Turner. However even the slightest exposure or ingestion of Jacob’s cum, be it topically, orally, vaginally, or anally still causes the female partner to be in a heightened state of constant arousal and crave her partner more. The only real way to satiate the desire is direct internal injections of his sperm. Unknown even to the doctor and DA Turner however, is the close relation of two of Jacob’s partners. The close genetic affinity has increased the side effects even more (nearly tenfold), so that the real only effective way to mitigate Jacob’s, and the infected Karen’s and Rachel’s condition is continued inseminations—come what may in the physical, moral and fertile repercussions.
