There’s a caller that enjoys to tease his ladies and make them practically beg for full on intercourse. He wanted to keep one woman waiting for the better part of a year before actually fucking her, I’m surprised most women would wait that long, but he seemed to enjoy it. Non penetrative sex was something he would get into, he’d tell me all these details about how he’d sensually drag his hard cock up and down her wet slit driving her crazy and she’d be so wet wanting him to slid it inside of her.
Some are just more into the foreplay aspect of sex than sex itself, so they do things like this or concentrate on oral and intercourse is the rarity for them, they like all the side dishes much more than the entree. Hand jobs, titty fucks, foot jobs, all of these things are sex in a way, but certainly not intercourse or for some as emotionally satisfying, sometimes you just want that penetration and intimacy than non penetrative sex act can accomplish.
To some it will always only be foreplay and not something you tease your partner with for nearly a year before letting them have it. Waiting a while can heat things up for sure, hopping into bed on the first date is usually not going to lead to a long term relationship, but pushing some waiting time longer than your partner is willing is just going to drive them away. Some feel a couple of dates is long enough, others a few months, but for some the no cock in pussy rule can lead to many variations of the non penetrative sex.
