A fleshlight will definitely change up your masturbation session. You will be excited to try it out and a lot of them look very realistic on the outside since they cast actual women's external genitalia for the molds. You should expect to not last very long and should orgasm very fast because they tend to simulate and grip your penis more intensely than using a hand.

They did not have fleshlights when I was a virgin.

If you are a virgin you will think that it feels super but compared to the real thing it lacks in several important categories. One and most importantly they are not warm/hot. The coldness is the most negative thing about masturbators. They are also not wet. Not lube wet. You can always add that. Real wetness whether it's vaginal or oral. Lastly, they don't have the odor. Whether we realize it or not smell plays a big factor in sex. Not is an obscene way, but the chemicals the body releases during sex appeals to people on a more instinctive level. Plus women can control the pressure of their orifices during sex.
Will continue later.

I would say it feels the least like oral sex because you really cannot replace or mimic the tongue well. Fleshlights mimic anal sex the best of the three due to the overall tightness of the experience.

Fleshlights do feel better and are made with higher standards and materials versus your typical masturbator. They are worth the extra money to get one if you are in the market for one. I rather spend a little too much on something and have it work than a little less and it can't do the job.
