The average couple looks forward to lifelong of sexual bliss once their love for each other is confirmed and established as genuine.
It was therefore a shock for a man who discovered that his wife suffers from a rare medication that has made sex a risky venture, as the wife regularly faints during sex.
Described as Postural Tachycardia Syndrome, the rare medical condition, doctors say, causes the victim to faint suddenly whenever sex is ongoing.
Twenty-eight-year-old Laura was diagnosed with the debilitating in 2011, and her first pregnancy allegedly triggered it.
Her doctors warn that Laura's heart maintains 40 beats higher than that of the average person, with a whopping 110 beats per minute.
Worse still, her doctors inform, when Laura gets down to have sex, the adrenaline and excitement can cause her heart rate to peak to as high as 180 beats per minute, causing her to faint suddenly.
Generally, a normal resting heart rate for adults ranges from 60 to 100 beats a minute; while a lower heart rate at rest implies more efficient heart function and better cardiovascular fitness. For example, doctors say, a well-trained athlete might have a normal resting heart rate closer to 40 beats per minute.
Narrating her ordeal, Laura said, "said: “Whenever I have sex, there’s a 50/50 chance I’ll faint. The fainting can happen anywhere, any time; but with my medical condition, it’s usually a case of gravity taking over, so the best way for us to do it is missionary, with me lying down.
"The first time it happened, it was a massive shock for both of us. Ben Crow (her husband, also 28) gets very upset each time, and when I wake up, he is very distressed, even though he never continues with the sex whenever I pass out.
"Once I faint, I don’t know what’s going on; but it’s very traumatic and worrying for my husband."
However, it’s not just sex that makes Laura to faint. Other triggers include sleeplessness, temperature, laughing, exercise and anything that causes her heart rate to increase, such as watching a horror movie.
The couple however assure that the challenge has not affected their marriage.
