you will have nothing to worry about, the aim of the game is to ride out, ride home, enjoy.
it doesn't matter what ride you do, be it, friendly, small bimble, evening trundle with mates, early morning run, trip to the shops, RTTB etc, etc, etc
you should always ride at your pace. the thing is this...
there will always be someone faster and there will always be someone slower - it doesn't matter. the only persons pace you need to concern yourself with is your own.
if you feel that you are holding someone up, mnove to the nearside a little, if they feel they want to pass then they will. who knows they may actually be riding behind you because they like your pace or your lines.
generally on here and other sites i think, there are no riding gods. we all started by getting on a bike and wobbling, stalling, locking up brakes etc. so don't feel that you are doing anything wrong - you aren't, i believe it's called learning the ropes.
ask questions on rideouts, talk to other riders and see if you can tag in, it's the way we learn. i learnt from following the likes of dynamight,very smooth rider indeed, doesn't like using brakes - increases observation and road awareness.
there are lots of little tricks and tips that riders can pick up from other riders on any rideout that you go on, never feel like you can't ask a question.
we are all bikers together, it's al about enjoying the hobby.
oh yeah, and tea/cake stops
