I've had "streaks" like you mentioned. I think the confidence from a successful conquest makes you more direct confident and less hesitant. I recall a number of occasions while travelling to or from an LTR rendezvous, I had other women definitely interested.
Stopped at a grocery store on my way home from a weekend fling. Woman makes eye contact with me in line, we chat, walk out together, kisses me in the parking lot and gives me her number...
On a flight to go on a camping trip meet a woman as we are getting ready to board the flight. She comes up to ask if we can get together when we reach our destination. I had to break it to her that when we got there, I was meeting someone. She still insisted on giving me her number.
Running down off a mountain one morning I meet a woman I was friends with who was leaving the state to live with her "love of her life" later that week. She laid a lip lock on me as we were both standing there sweaty and breathing hard. Later that day another woman friend/client did the same thing. Man what a day!
As a friend says, never say WHOA in a horse race...Enjoy the streak and don't overthink it.
