Self - Confidence

Im 16, I ’ve masturbated (by rubbing my clit) for about 2/3 years now and it always feels good, I want to make the feeling ‘real’ and actually go through with being fingered or having sex with a boy but I’m just nervous about everything! Like smell, wether I’m too tight etc. I have gotten with 20+ boys at parties- I know I’m ready for it and I’ve had so many opportunities, I think i think it is more of a deal then it actually is and once I do it I will be more comfortable with my body- I just am lacking self confidence:( help!
