English: Male masturbating with the use of a sex toy. The penis is thrust in and out of the tight enclosure, providing sexual stimulation. The sleeve stretches to surround the penis, but lubricant is needed. The artificial vagina can be moved manually by the person who is masturbating, or can be anchored and the man can thrust in to it, similar to sexual intercourse. Ejaculation happens within the toy and it must be cleaned after use.
