Glands swollen

This may be really crazy for me to ask.. I'm being serious so don't judge. But I've been having problems getting infections and my glands have been swollen alot this year. I also started giving my SO BJ's and swolling. Is it just a coincidence that I get infections since I started or could that be why?? I can't seem to figure out why I keep getting them and they are so annyoing having to take an antibotic for it every other month or so.
