To answer the question ,yes it can be painful.

Don't worry though because all you need to do is experiment a bit with
fingers/dildos/lubricant and your hole will eventually stretch and you'll be able to enjoy it.

If it's your first time don't hesitate to tell the girl to take it easy,she'll understand.But you need to open your hole a bit by yourself first otherwise it's really a turn-off for a girl to try to fuck you on an absolutely virgin asshole.Unless of course she has the time and the taste for it.
