This doesn't sound like a disaster to me, you don't need a doctor, rather you need to co relate your situation with some knowledge sharing here. If what I say relates to your situation, you have the solution.
After marriage every woman doesnot start having orgasm, that old fear of is he good enough, am - good enough, does he suspect old affair, what if he knows, is he on paid sex, how to know I am making happy, there are 100s question keeps a girl bogged down. Out of 4 years, you got him for 4 months, its likely your mental barrier still is there. I fucked a girl once, she admitted 1st one year she had sex, but still in a haze what she was doing.
For orgasm, either internal or external stimulation is needed, either on G spot ot on Clit. Maybe your husband didn't give much attention there, rather focused on his need. Give him time, talk on what you are looking for, things should be okay. Your earlier 16 year guy must be good enough to give enough time to stimulate you.
And finally, request to complete the question on a comparision on their foreplay, time of intercourse, how was the tool etc. That can shed some light on what one did right the other didn't. Personally, I don't see any problem with you.
