Getting into roleplay!

What hfilled said.

Since RP is just talking to another person there should be a way for it to be fulfilling for everyone with the exception of social-phobics.

But I would say to try and take as relaxed an attitude to it as possible. If either yourself or your partner is either trying to introduce elements that don't turn the other on or trying to exclude elements that are a must for either one of you, then it won't work; it's really about finding the right person, whose desires match your own.

For instance a lot of people say that there are elements they can either take or leave in an RP. I love popping and sometimes there are people who say 'I don't really care for it, but I can  RP it if you want to'. It might sound like they're being very accommodating but in practice it just won't work, they won't be into it, I'll know I'm not going to get a response from them about it and the RP will be un satisfying for us both, even if it does seem like such a little thing we differ on.

And as hfilled says, both people have to write varied and descriptive accounts of the role play. Description is the key, or you won't feel it. Describe, and encourage your partner to describe all the feelings, sights, sounds etc. that go along with the inflation.

And just relax and be conversational, don't try and stick to supposed RP conventions, be prepared to wait a few minutes for a response, but don't just disappear without saying anything either.
