Yes, it is safe to suck pussy as long as proper hygiene measures are taken. It's important to note that, like any sexual activity, there is a risk of transmitting sexually transmitted diseases (STDs) from sucking on a pussy. To minimize this risk, it is important to practice safe sex using protective barriers such as condoms, dental dams, or latex gloves.
