After the " my Life is in bits" thread it's nice to see you back in the saddle but in future we may start charging you for advice LT.
Both these have worked in the past.
I was in a similar position but I was blessed with a close Female friend who was up for anything! Cue me and physcho cosied up for the evening when by pre arrangement Vicky; my friend lets herself into the House using the spare key and marches straight into the Living Room.
Me........ "Vicky, please it's not what it looks like"
Vicky..... to physcho, " Dont worry love your not the First and you wont be the last." A sharp exit from physcho 1.
Game over.
The second situation. After having sex with a similar type she went into the Bathroom. I followed her in and told her that although the Sex was very nice it wasn't what I was really into. I then asked her seeing as we were in the Bathroom if she had ever tried Watersports. Needless to say unless She is a real pervert and physco 2 wasn't ( a possibility yours might be) you will have hit on another winner.
