Title says it all. I have a beginners set of plugs, and even though I'm totally fine when lying down sideways, whenever I'm sitting down it always starts to hurt my sphincter. I've tried using more line but it didn't help much. I really want to try casual wearing of plugs, but can't when it pains me to sit down
Also, what are the toys made of? Yes that does matter, as does price. You get what you pay for and cheap toys aren't really that good. You want a soft, flexible toy for longer use.
