The above reply is true. For the first time, it will be painful
for both of you as it's a new experience.
For sex education purposes, if you do not plan
to have kids, please practice safe sex i.e. use condom. For 1st
time experience, choose a day out of the ovulation period and
engage without condom.
Answer to your second question, no, by the time you get excited
enough, you and your partner would have produce enough lubricant
for penetration. It will be painful if you force penetrate in when
there is not enough lubricant secreted.
