Bit of backround for you, this is a fairly new relationship, he's a nice guy and wants everything i want from life but AIBU...... to finish with him because his willy is too small for me to get any satisfaction 
Ive been in relationships in the past where they have had sexual problems/issues and it's soul destroying, i've also had very satisfying sexual relationships so i know what it can be like.
Opinions please.............
