Fouls (II.E): It is the responsibility of all players to avoid contact in every way possible. Avoid contact in every way reasonable possible, while still playing Ultimate. Some contact is inevitable, but players have an affirmative obligation to make reasonable efforts to avoid contact.

Safety is paramount. We want to avoid injuries.
If your experience is mainly in open and you are playing in an AFDC league you need to adjust to playing with ladies. You need to make every effort to ensure your play doesn't hurt them or anyone else. Sometimes this means you don't get the D because you have to pull up. Or it means you can't lay out. The same goes for older or less athletic leaguers or minors. If you can do something to avoid contact you have to do it. Its your responsibility.
Having fun and not getting injured >>> making that play in a game on a week night.
Be aware that not everyone on the field plays at the same level and respect that.
