Sex Advice!!

Hi everyone, I am a long time reader of this site and felt like asking a few sex related questions..

Am meeting my girlfriend after a long time. (Long distance thing)..
And we're going to spend a few days together alone (pretty much locked in a room) being with each other (switching of the phones and everything)..

Now first of all, she is a little allergic to condoms (or having lots of sex with condon on) and as much as I'd like to get it on without a condom I am not totally comfortable without it (mentally).. I think it's the make (type egs. dotted and lubrication of the condoms that makes her have that burning feeling inside).. But is there anything I can do to ease her burning?
Also, what do you recommend being the best thing to eat and drink (for me and her) so that we can enjoy a very healthy sexual time with each other for a few days (yeah we're both approaching 30 and arent doing it first time, but we're meeting after over 4 months and that too first time in 6 months that we're spending a few days alone)..
We love each other madly and eventually NO sex is more than okay with both of us, but we're quite wild in bed and have mad craving for each other due to the long distance, any insight and suggestions on this situation would be helpful..

BTW, one more thing, she only cums, when on top which is great.. But when I am on top of her and put her legs on my shoulders and go deep .. I can feel an insane amount of warm wet discharge coming out of her and she loves it too, but she's not having an orgasm.. What is that? Sorry to bombard with so many questions, but I am just excited to see her :) :D ..
