Asymmetric breasts and relationships

Hi Ladies

Not sure if this is the right area of the forum to post this but thought it would be a good starting point as it's the general bit!

Basically I have severe asymmetric breasts. I have been saving for a few years to have an op and I need to lose a bit of weight also before I have it done so I'm looking at next year at the earliest. It really knocks my body confidence and I've been single for the past 2 years mainly due to this issue. Recently I met someone and we've been on a couple of dates. I really like him but am starting to panic about being intimate. I really really do not want to show him my breasts, I could cope with wearing a bra during naughty time (!) as i have mastered padding etc, but I really could not get the baps out in front of him 

Does anyone have any advice on how to approach this, perhaps been in a similar situation or have any tips? I really don't know how or even whether to explain the situation to him. He is a nice guy but I really don't want it becoming a big deal.

Thanks for reading lovelies
