The 19-year-old was included in the Netherlands Under-21 squad for the first time during the November international window and made his debut in the 3-0 victory over Denmark in the first leg of their European Championship play-off.
Born in Haarlem, Bouwman has represented the Netherlands at several youth levels, having progressed through the country's international development system.
However, his family background means he has other options should he eventually be considered for senior international football. His mother was born in England and is half-Jamaican, while his father is Dutch.
Speaking to Voetbal International, Bouwman confirmed that he could represent England but made no secret of his preference.
"I'm in a great place with the Netherlands," he said.
"I've played for all the youth teams here. England have also never really made contact. So the Netherlands are definitely my first choice," he added.
The defender's comments suggest that he has little interest in pursuing an alternative international career despite his eligibility.
Bouwman's immediate priority is to continue developing at Ajax and help the Netherlands Under-21s qualify for the 2027 European Championship in Albania and Serbia.
The young defender has already experienced disappointment in previous youth campaigns, having narrowly missed out on reaching major tournaments with the Under-17s and Under-19s.
"It was always just short of being enough. With the Under-17s and Under-19s as well, unfortunately. That was disappointing, so this time it has to happen," he said.
Bouwman believes the Netherlands have the quality to overcome Denmark and secure their place at next summer's tournament.
"Denmark Under-21s are a difficult opponent, but with our team it should be possible. We've studied the opposition well, so hopefully things will go well in these two matches," he said.
The first leg has already given the Netherlands a commanding advantage, with a 3-0 victory putting them in a strong position ahead of the return fixture.
For Bouwman, the call-up and debut represent another step in his progress after establishing himself in Ajax's first team. His comments also make clear that, despite having other international options, his ambition is to continue representing the country where his football development began.
