Will i appear/feel like a different person after having for the first time?

so, im 20 and still a virgin. im also a male, so whenever anyone finds out about this they're pretty confused, because i do seem confident and better looking than most people. the thing is that up until about 18 years old i was very nervous around anyone and i didnt have much friends, now ive been through a few jobs and currently make $11.50 an hour and have my liscense and ged. (drop out) lol woops zzzzzz... ;) but anyway, i feel like ive accomplished a lot of the big things in life besides having . ive gotten to first base with a few girls, but im still a virgin. anyway though, my main question here is will i become different after having for the first time? i mean, will my confidence or the way i talk to people change? this might be a weird question to ask, but please, only give me serious answers from people who know what they're talking about. lol. (i dont want someone dissing me for being a virgin and i dont want someone to answer thats still a virgin themselves.)
