Does having sex without a condom feel better for both boy & girl?

Perhaps not, since condoms are often lubricated which can make things smoother :)

Yes, it feels so much better. The best way to make the vagina and the penis lubricated enough is by giving the guy a blow job and letting him rub his penis around until it's nice and wet. After that, it's really easy to just go at it and not have too much trouble, except maybe the penis slipping out cause it is too slippery down there. It is an indescribable thing that you really just have to have your own opinion on, and you won't know until you try. Just be safe
