First of all I’d like to praise you for still being a virgin, its something to be proud of! You have clearly expressed your interest in sex, now, as you said you have reached a point where you feel happy with your figure. This self-confidence will be a helpful factor, when you are ready, to evolve your sex life into a healthy and for filling one.
Don’t succumb to social pressures or other people’s assorted ideologies. You are the master of your own destiny, so make sure these great decisions you make are correct for you and are happening at the right time.
Your first sexual experiences and your first sexual partner is one that you will always remember, so choose wisely! Also this is both a physical and mental journey for you, a milestone you should look upon with great anticipation, not a spontaneous or brash decision.
Bide your time and make sure you are experiencing your first sexual encounter under your terms, in a safe, pleasurable and comfortable environment. Waiting for the occasion and when the moment in time is right for you.
