how many of you .. after Fucking for 45 min+, cum in the girl, and ur Dick still hard after cumming? n 5-10 mins later still hard n can start Fucking till cum again? this girl makes me so horny

as grow older will become be less horny or dick cant hard for 2 hours straight already..?
or do some of you cant control urself not to cum until after 1/2 to 1 hr of sex (though you felt like after 10 minutes)?
maybe try stop ejaculating halfway when u orgasm, so some sperm is left .. and you can Fuck till orgasm again multiple times.. as we can orgasm if there is a little sperm left or replenished after 10 minutes i think
then usually around how long of stimulating the Clit then the girl orgasms? circular motions is best right ;; sometimes the girl doesnt orgasm is it cuz i wasnt at it long enough?
how many of you can recognise the g spot when you feel it? its like a spongy bean when you press upwards inside her Vagina right? about how far in is it..? what % of the length of ur fingers?
