What To Do Lounge?

There is a girl I talk to occasionally who really likes me, shes pretty much said she'll fuck/suck/experiment whatever with me because shes deadly curious, but only if we're dating.

Now she's alright, 36C/D, pretty slim, horserides, however, she is pretty fucking ugly. I dont know if I could do it without her looking at me killing my boner...

Should I ?
