i have received the very same feedback from girls i have had sex after a break , and when i have been jelqing
meanwhile. it really makes me - especially thicker , but longer also, because it makes me HARDER: for me it takes some time before i get fully hard, it happens usually during intercourse only (many have said they love the feeling the dick growing inside). and i think this is the case for most big dicks , at least according to big dick porn where guys have obviously difficulties to get fully hard. so from this part, the story is credible to me .
because i have similar problems at the moment, i sincerily hope that the old recipe of just trying to be sensitive & understand her sweet spots, but also the ways you can hurt her, will get your sexual chemistry working - then the fun starts.
ps: about petite girls having small pussies - this is really not the case: the size of body doesnt tell anything about how much girl can take inside.
