KG, continue to proceed with caution as you are.

With W staying the night have you kept in mind that she has (I'm assuming) not been tested? Please please keep your health as your #1. Be willing to be careful, and be willing and brave enough to have the conversation and stand firm. This is widely under-discussed in the lesbian community, and too often swept under the rug. We can't do that to ourselves.

I'm sorry to harp on this, and you don't owe us a report on the topic. But sometimes when I look back at my own choices in life I wish I had not feared the embarrassment of the conversation.
