ok. my contribution to this is that im not bi...... my mouth and cock are. I dont fancy men but i enjoy bi play in a MFM 3sum. I enjoy it to the point that i look for couples with a bi male more than straight couples but i could never see myself in a relationship with a man or meet a man alone.
What an excellent perception of this.. A very good way at looking at it/thinking about it..
