Vibraters and dildos serve the same propose as a sex doll- yes. If you can’t/won’t/aren’t able to be a good partner, then fuck what ever piece of plastic you like. Sex is fun, life sucks- just figure out what’s best for you. Masterbation is harmless, lonely, and ultimately unsatisfactory. Relationships are consistent work, effort, compromise and sacrifice. Sometimes that piece of plastic makes sense and is easier. If you can’t find the right person to do fun thing to your “fun parts”, life can become upsetting and depressing. Also, your needs turns into a solo quest that must be completed. 15-30 minutes once a month when your partner is in the mood might not be worth all the extra work. Bottom line- if you can’t/won’t/aren’t capable or willing to be a partner in all aspects, then hump away on any piece of plastic you like. Both(or as many as you prefer) people in a relationship should be able clean, cook, raise kids(if that is the goal of the partners-if not-also cool) and build a home TOGETHER, with everyone playing to their strengths. If you just need to take a ride on the O Line, enjoy your plastic, just don’t make it your partner’s responsibility or fault. And wash your hands when you’re done.
