It depends on the situation and characters for me. If I'm writting about a cute, virginial nun-like girl I'm going to use either clinical or romanic terms. Likewise, if I'm writing for an earthy, rough, horny tomboy I use soft- and hard-core terms.
Hello there. I've been a member of AdultFanFiction.Net for a while now and even submited a story, but this is my first time posting on the forum. I don't know if I'll post all that often but we'll see.
