To give or to not give a BJ?

3 years in a relationship! I can give a BJ, but not sure i like giving one though! My partner has no complaints and genuinely understands that i am not doing it wholeheartedly because i don't seem to like the idea of it.

But all of this just puts me on guilt-trip a few times! I don't understand!

Open to suggestions to make it likable/lovable/enjoyable for both in comments!

Thanks.
