Aspie guy, just 41, act and feel 20; and that's an overstatement.
Ability to make anyone comfortable, totally passive but switch with the right person, experienced at therapy, naughty minded, no hangups, few inhibitions.
Highly clever, often sought out for talks with professors and the like. No real type, I fancy who I fancy.
A day or forever, loyal, attentive. Can be assertive if you require.
