Communication is key. Make sure you and your partner talk about your expectations, boundaries, and any concerns you might have.
Safety is crucial. Use protection to prevent unwanted pregnancies and sexually transmitted diseases. Also, be in a comfortable and private environment where you feel relaxed. You should also be emotionally ready and with someone you trust and care about.
One should remember that it's normal to feel nervous. It's a new experience. Be patient with yourself and your partner. Respect each other's feelings and bodies. Don't rush into it just because of peer pressure or any other external factors. It should be a consensual and enjoyable experience for both parties.
