Help!

Okay so both my boyfriend and I are kinda shy... sex is amazing, only guy who’s ever gotten me where I need to go if y’all know what I mean 😏 but recently foreplay has gone out the window... it’s been months since the last time he went down on me. If I’m on my period and we start getting frisky I always please him but it seems like he doesn’t want to do it for me. I’ve tried sexy lingerie to try and spice it up but we’re both so shy that it’s just straight to sex. Should I bring it up? Should I tell him I want more foreplay? How do I start the conversation? Help 😭
