Dildos
An ejaculating dildo is a toy that reproduces the final phase of intercourse by releasing liquid from its tip. Internally it has a reservoir at the base, a narrow channel along the shaft and an outlet at the top. Squeezing the base shoots the liquid through the channel. Some models use a syringe system. This is mainly a fantasy and role-play product, not for functional use.
Real semen is not used for filling. Suitable options are water-based lubricant, commercial "fake cum" solutions designed specifically for this use, and more rarely homemade water-and-starch mixtures. Homemade solutions require immediate cleaning so they don't leave residue in the internal channel. Avoid foods like dairy or oils, as they come into contact with sensitive tissue.
An ejaculating dildo is not designed for medical use or conception. It is purely a fantasy toy. For assisted home insemination there are dedicated kits from pharmacies, with a collection cup and a special syringe. They are used on a doctor's recommendation. For fertility matters, the right person to talk to is a gynecologist or an assisted-reproduction center.
Cleaning the internal channel is the most demanding part of care. Fill the reservoir repeatedly with lukewarm water and a mild sex-toy cleaner and squeeze so the liquid passes through the whole channel. Repeat 3-5 times until the water runs clear. Cleaning right after use is important, especially with homemade solutions. Dry it fully either by pumping or by leaving the toy open for 24 hours.
An ejaculating dildo suits users interested in specific scenarios where a visual climax plays a role. Common use cases: breeding fantasies, role play involving a partner, or cinema-inspired scenarios. It is also used by visual content creators. If such uses don't interest you, a classic realistic dildo offers the same penetration functionality with simpler care.
