**The Safety Valve of Modern Sexual Desire: Analyzing Internet Sexual Risks, the Evolution of Condoms, and Male Vasectomy[i]**

**

In today's society, the internet is a frequently used channel for finding a suitable sexual partner[i]. However, finding a sexual partner through such electronic networks can be dangerous[i]. According to a study published in the Journal of the American Medical Association, people who find partners online and have sexual relations with them have a higher risk of contracting sexually transmitted diseases[i]. The survey showed that 16% of sexual partners were found online, and these partners often had multiple sexual partners, frequently engaged in oral sex, and often had sexually transmitted diseases[i].

The development of effective contraceptives for men lagged far behind that for women[i]. Forty years after women had access to the birth control pill, men still had to choose between condoms and sterilization[i]. Condoms had long been used as a preventative measure against sexually transmitted infections[i]. Early condoms were made from animal intestines or fish skin and were not very effective[i]. From 1840 onwards, vulcanized rubber was used, and from 1930 onwards, latex was used[i].

Condoms not only prevent pregnancy, but they are also the only contraceptive method that provides reliable protection against HIV, and more importantly, they have no side effects[i]. Some men complain that their sexual arousal is reduced when their penis is inserted into the vagina with a condom on[i]. However, condoms are 100% safe when used correctly[i]. Condoms with damaged packaging or purchased from vending machines (due to temperature differences causing aging) should be used sparingly[i]. Currently available materials include latex and polyurethane for those with latex allergies[i]. Condoms made from animal intestines should no longer be used because the small slits in the intestines, while preventing sperm from passing through, do not prevent the passage of HIV[i].

Vasectomy: This is a simple surgical procedure performed under local anesthesia to achieve permanent contraception[i]. During the procedure, an incision of about 1 cm is made on each side of the scrotum, and then the vas deferens is removed and a section of about 1 cm is cut off from each side[i]. After the surgery, sperm produced by the testes can no longer enter the semen and are absorbed by the body[i]. This procedure has an effectiveness rate of over 99% and does not affect sexual desire, sexual ability, or penile erection, nor does it affect the production of the male hormone testosterone[i]. The semen ejaculated by the patient retains its original color and viscosity, but there are no longer any sperm in the semen[i].

It is important to note that vasectomy is not immediately effective after the procedure [i]. After surgery, some sperm usually remains at the end of the vas deferens, and this residual sperm must be expelled through multiple ejaculations [i]. Therefore, three months after the surgery, a semen analysis must be performed (to check for the presence of live sperm). Contraception is considered successful only when the semen is completely free of sperm [i]. This procedure is theoretically reversible, but the procedure is quite complex, and the success rate is only around 50% [i].
