.....Although bareback is the natural & fun way, it isn't the safe or logical way when having sex with individuals you hardly know, or who are having sex with others they hardly know. With bareback, you indirectly fuck everyone your partner has/is fucking ... not good or wise. Some STDs, such as herpes, are incurable and basically make a woman unfuckable by bareback, once the disease is acquired. Although painful for both men & women, it is particularly painful and inconvenient to women as the lesions are often internal and also undetectable to the unaware males.
.....So, unless you know your partners really well, safe sex is the only way to go. One in five sexually active individuals between age 16-39 have a STD ... imagine having bareback sex with 5 different individuals where one is probable (due to the odds) to have an STD ... its basically Russian roulette, and if you play that game enough, you bite the bullet. The risks are as clear as one's abilities to separate reality & fantasy, and the penalty often irreversible, ruining your sex life for the remainder of your life. To me, it simply isn't worth it.
