what is sexually Transmitted Diseases (STD) ?
Sexually transmitted diseases (STDs), or sexually transmitted infections (STIs), are infections that are passed from one person to another through sexual contact. The contact is usually vaginal, oral, or anal sex. But sometimes they can spread through other intimate physical contact. This is because some STDs, like herpes and HPV, are spread by skin-to-skin contact.
The diseases which are transmitted through the sexual act or sexually are called sexually transmitted diseases.for eg HIV, syphilis,gonorhea etc.since the sexual act is an intimate connection of two bodies together therefore there are more chances for getting transmitted to normal person.
