It sounds like perfectly normal, male parrot behavior to me, from a male bird that is closely bonded with you. My male Senegal parrot is exactly the same as your Lovebird, he does "heart-wings" for me like a female typically does, he's constantly regurgitating and head-bobbing for me, etc. I brought him home when he was 13 weeks old, and I am the only person in my house so my birds are all bonded with me (and I have no 2 birds of the same species, so none are really bonded with each other, they tolerate each other and sometimes hang-out together on their big play-gym, but otherwise they are on me). Kane started acting hormonal with me at puberty, which was just about 6 months ago when he turned a year and a half old. And I have found the best and really the only way to deal with it is to simply put him down/take him off of me when he starts this, let him cool down, and then let him with me again. You don't want to "punish" your bird for hormonal behavior, as it's not his fault, but just putting him down on his cage or a play-stand whenever he starts acting that way will eventually teach him that it's not going to happen with you...but you have to commit to doing this every single time he starts doing it for him to get the picture. Otherwise he's just going to continue doing it...
So no, it's not at all unusual behavior from your bird, he's just closely bonded to you instead of being bonded to another Lovebird/bird, and he's hormonal, so those feelings are directed at you.
