Im a 25 yr old female and not sexually active. I was active when I was 21-23 yr old with my boyfriend at the time. The strongest and best orgasms was from sensual and gentle real life sex. I guess it has to do with the emotions around actually being with a person. oral is second best, but only if the guy is skilled masturbation is nice and I can achieve orgasm rather quickly. With oral sex or masturbation, the orgasm is better with either a finger or toy "up there" so that the walls of the vagina have something to squeeze against.
