Sex is good.It is also wonderful .The feeling of climaxing during sexual intercourse or any other form of sexual activity is always mind blowing. Research studies have shown that during an orgasm,the brain releases so much dopamine that a brain scan resembles that of someone on heroin.This is to make you understand how great it’s effect is.

Orgasm is the expulsive discharge of accumulated sexual excitement during the sexual response cycle,resulting in rhythmic muscular contractions in the pelvic region and this gives a feeling of sexual pleasure.

Being one of the intense pleasures mankind has been blessed with,yet it’s mechanisms are either misunderstood or poorly understood.
The clitoris the bulbs of the vestibules and the penis are erectile tissues.During sexual arousal, nitric oxide (NO) is released from parasympathetic nerve endings near blood vessels within erectile muscles.The release of NO activates a signaling pathway that results in relaxation of the smooth muscles that surround the arteries causing them to dilate.
During orgasms,triggers by genital stimulation are sent to the brain through the autonomic nervous system. The pelvic floor muscles contract rhythmically in unison,usually at a frequency of 0.8 per second for 5-8 contractions.These contractions are usually associated with the peak of sexual pleasure.
In the males,once stimulated sexually,frictions in the glans penis and other stimuli,signals are sent through the nervous system that results in ejaculation.When the mental/physical stimuli has attained a certain threshold,the spinal cord emits sympathetic impulses which leads to orgasm.This occurs as peristaltic waves that push sperm by the contraction of the epididymis into the vas deferens.Muscles surrounding the urethra contract and propel semen out of the penis.And the muscles in the neck of the bladder contracts to prevent semen from flowing backwards.

As much as the health benefits of having orgasms are numerous such as improving sleep,decreasing effect of stress and decreasing the risk of incontinence as well as lowering the rate of mortality.
However, there has been growing concerns over the effect of orgasms on the heart.Orgasms in sex causes a massive form of excitement in the body as this body recieved signals from the brain.This mental/physical stimulation increases the adrenaline rush in the body which has great effects on the heart and cardiovascular system.
This adrenaline pump/rush can trigger heart attacks and arrhythmias due to the heart’s abnormal pumping rhythm. Although there is an increased risk for older men to have these attacks or hypertension. And sex in this case doubles this risk.

With the introduction of Sildenafil( Viagra) ,the incidence of heart attacks or cardiac arrest is on the rise as it puts a lot of pressure on the heart.Sex is part of our daily lives,and in order to maintain a healthy heart and lifestyle, certain things must be avoided,amongst which is smoking. Also having a good diet and exercising frequently increases one’s life span.
