From my personal experiences of 40 years already I still discover deeper roots of my Dominant sexuality and no sexuality.
I discovered that nonsexual submission fulfills me much better and trust me not because I am too old and unable to but because I am in good health part of it is by masturbating daily just bringing in mind one of my pets' subs, I had the pleasure to be involved with.
Ejaculating is freeing and seductively relaxing.
Learning and discovering never ends especially if we have peace of mind and are caring to each other.
Nonsexual submission incorporates the deep depths a sub can enjoy and feel making her kinky Dominant feel proud of her.
