18 with a then 16 (or 17?) year old gf. First for both of us. I think she liked doing it but didn't like the end result. That was the only one I had (this was 1995) for, oh, probably a year, and then got intimate with a new gf, who was (is) a couple years older than I, and she did it and LOVED doing it.
After that it was a while again before a woman did (and then, it was mostly mouth and hands with the climax ending in her hand or on her or me, if you get my drift).

It's now been 3 years since it's been done and "swallowed."

(my preferences for going down on women have been stated elsewhere ).

No, readytogo, I've NEVER done it with a condom on, flavored or otherwise.
