My preference is older gentleman.
From past experience, the younger guys are obnoxious, annoying, disrespectful and clingy. There are VERY FEW under 30 that I do see, but it is rare.
I have found that based on the length of my sessions, I have enjoyed the company of an older man with similar interests in conversation and experience in the loveshack.
I will take a silver fox with AARP and Dad-Bod everyday rather than a boy who stills smells of similac and is trying to take me to pound town. No thank you.
