Is it normal to get aroused easily, cum slowly and then stay aroused?

I'm a 21 year old male, slightly above average length and girth like 6-7in long and like... pretty thick.

now in porn or implied on tv and in movies other men worry about having a short or thin penis, not being able to get hard or stay hard, unable to have sex for very long, and getting flacid immediately after

I get turned on really easily, if I see anything sexy I start getting rock hard

when I masturbate I last about an hour or 2
when I have sex (I have yet to have any girls stay long enough for me to finish despite not wearing a condom every time) I last for atleast 3-4 hours, they come a few times (4+ times) durring that period

after I do come I stay hard

I've only had a few sexual partners so it's not like experiance

I've tried to google this to see if this is really unusual but from what I've found, at most men only have one or two of these

is this some type of gift I should be proud of?
is this the apex of what women desire sexualy? (besides things like personality and body) if it is what do I do with that knowledge? I mean its sleazy to pick up women by bragging about your sexual prowess, so should I be keeping it a secret until we are already having sex?

just looking for some answers
