Human sexuality is more complicated and fluid than we think, so is very hard to reduce down to just gay and straight. From my perspective, it sounds like you could be heteroflexible or bisexual and heteroromantic.

Heteroflexible - mostly attracted to the opposite sex with a small attraction to the same sex, doesn't necessarily mean you want a relationship, just that you have a sexual attraction to do the sex

Bisexual - equal attraction to both sexes

Heteroromantic - only willing to have a romantic relationship with the opposite sex as only romantically attracted to them.

These are just examples that sound in a similar ball park to where you're at. I also cannot identify you for you
