I need advice from people who had sex before.

I’m F25 and my new husband is 30M, it’s our first time having sex in our whole lives.. “I’m asking here because we moved to an african small city for work after marriage and i don’t know their language or anything to ask:(“
we tried having sex together 6-7 times since marriage but barely a penetration happened after a long time of foreplay, maybe just half of his is inside after 4 times, when he tries my legs become very tense and my vagina feels too small and rigid and it is painful! Painful to a level that i have to stop him multiple times, the last few times were less painful (probably the tears healed) and he was able to insert small part of it .. but when he tries with his finger he can insert his whole finger but also feels like it’s very tight on it to a level he can’t rotate it (painful only at the beginning but not comfortable overall)
I used to know him for 7 years as a long distance relationship, we both were sexually attracted on phone, and i don’t know if this could be a reason or not but i go to the gym a lot and my whole focus is on my legs and i lift heavy (120-150kg)

My two close friends told me that this is weird and never happened to them when they tried, it took them 1-4 times to be able to do it

Did anyone experience the same? Did it work at the end? I know it may be vaginismus but can we treat it by just keep trying? I tried to take a muscle relaxant but it didn’t work at all, or could it be a thick hymen although he inserted his whole finger? Please i need reassurance or guidance or experience
