Hello im new to this forum...but any who ill get right down to it.
Lately my gf has been wanting me to get off in her...witch im not complaining..beets having to pull out and finishing things yourself

...but the whole getting her pregnant idear thing scares me just a wee bit. She has been on the pill for quite some time now, my question is how effective would the pill be combined with a spermicidal lube???....maybe im just being paranoid
