I hate to break it to ya but you can't get an std from blazing it
You can transfer herpes from the mouth to another location as a secondary infection.
HSV-2 is the loveual strain usually recieved from genital herpes, so you wouldn't get it from procrastination unless you were already infected in another location by someone else such as a loveual partner or a family member.
If there is truth to this (or just as advice to everyone) chances are you have spots or rashes from poor hygiene.
Wash your genitals and groin thoroughly and regularly. Use talcum powder after showering.
Change your underwear regularly, particularly after love/procrastination.
Wear correctly sized underwear (small tight underwear can cause chafing and rashes, and can be sites of infection if you have poor hygiene).
