Shoot.. it erased my detailed answer.. basically give him lots of prolonged head often to stretch the chambers.. make him take his blood pressure pills... and give him viagra and maybe enzyte. You might be stretched too... They have stuff on the internet to tighten things up.. dont know if it works... and try this.. you on bottom.. him on top.. put your legs together after he enters you.. then have him stradle you and go up and down slowly.. its great and makes it tighter for you both... the nerves are only in the first 1 or 2 inches of a womans vagina anyways. Some people just arent sexually compatable though. Never ever tell him he is too small or he will go nuts on you... cheat on you... who knows.... but things will never be the same... Never compare to your X... a woman should know that better than anyone.
Ive been with many women in my life and the 20 year old playboy bunny was like a cavern.. she was molested from age 8 to 13 and I think it ruined her.. I was with a woman 54 that was tighter than any virgin I had ever deflowered... I was with a woman in her 40s that had 5 kids and her gyno said he could almost get his whole hand in there. I tried.. It was like a wet bag... BUT.. she did the kliegels and was tight as a drum at the opening and we both still enjoyed sex A LOT... the inside didnt affect her. We are all different. Just make sure that if you are going to carry on a relationship that you are matched sexually as well as personallity, etc. or it will end up disasterous in the end.
PS.. High blood pressure, aging and drops in testosterone and not being exposed to womens pheromones all contribute to his drive and size. I know because Lilly answered a post to me that I put up worrying about my large size getting smaller after a divorce and not being with anyone for a long long time. Im scared to go at it again for the exact reason that you are writing about. But its all a matter of confidence and though I thought so she confirmed it..She gives good advice. Thanks lilly.
If hes developing ED... you had better get him to the urologist and keep him on blood pressure meds before the damage is done. Otherwise he will end up with an implant... Oh.. they do have a surgery for enlarging a penis.. it involves cutting a ligament that holds the base of the penis then they inject fat into it.. its gross and looks gross.. and I would never get it. Ewww!
Hope this helps!
Good luck.. and thank you Lilly.. you are a pretty smart and wise girl!
