Iron Rule of Tomassi # 2
NEVER, under pain of death, honestly or dishonsetly reveal the number of women you've slept with or explain any detail of your sexual experiences with them to a current lover.
The single most disastrous AFC move a man can make is to OVERTLY describe past sexual experiences and/or give a number (accurate or not) to how many women he's been with prior to the one he's with. This simple act, whether you offered the information or she dragged it out of you, ALWAYS comes off as pretensiousness and is often the catalyst for an avalanche of emotional resentment, if not outright emotional blackmail from an insecure woman. This is a rookie mistake that will only take you once to learn.
If a woman puts you on the spot by directly asking you for this information always sidestep this COVERTLY. C&F works wonders in this situation and still keeps the air of mystery and challenge about you.
Her: "So how many girls have you been with?"
You: "You're my first actually"
Her: "Really, how many girls have you been with?"
You:" You mean tonight?"
Her: "C'mon, how many girls have you been with?"
You: "You know, I really lost count after 50" (or something outrageous).
When a woman asks you this question she is seeking confirmation of what she already suspects - NEVER give her this satisfaction. When a woman resorts to OVERT communication (COVERT being her native language) she's generally exhausted her patience to be COVERT and this is a desperation tactic for an insecure woman.
Just so you know, you're in the position of the girl who asks this sh!t.
