Cis man with a question

What is your opinion on allowing partners to go outside of the relationship for sexual relief if you are asexual? I’m starting to see this girl who is asexual and I really feel a wonderful connection to her but I personally have a high sex drive. I was wondering if it’s common for people to allow their partners to get their desired out elsewhere, as I don’t want to force her to do something she’s repulsed by, but I also want to date her romantically. If it’s not OK that’s fine and I could deal with that situation but I just wanted to see opinions.
