I know this is an old thread, but I think....when you are in your late twenties, that is old enough to handle sexual intimacy differently. What you guys did, with the whole, "2nd Base" thing, reminds me of teens.
At your age, it seems it should be understood that if one is not ready to have sexual intercourse, then letting a man finger you and then go down on the next date is extra and a bit much because at your age, you already know what you have to offer sexual and, until YOU feel it's time for the full monty, there is really no need to allow any kind of "sampling". And, that's what went on...the type of "sampling" that younger people do when they are trying to convince one another or themselves.
If I'm not ready to have sex with you, you WILL NOT be touching my bare cookie in any way, shape, nor form, whether it's with your fingers or with your mouth. I don't see the point in that but to get all worked up for no reason....as I said, it seems almost as if it's to prove something to him or to yourself.
If you're not ready, you're not ready. Period. So, the BRAKES have to be put on when dude starts trying for your crotch. That's just my humble. IDK what his reasons were for disappearing, but for YOU and what YOU like and want, I think you will feel much more at peace in the future if you stick FULLY to your convictions. Oral sex is sex. He gave you oral sex. I would even argue that fingering is something approaching VERY close to a form of sex. You went back on your conviction and so when he disappeared, you were left holding the bag.
Stick your your convictions and don't allow your boundaries to be breeched until you are fully ready.
