For ten years, I've shared a house in a large eastern city with a number of college and post-college graduates who were working as interns or had a new and good professional job starting their chosen careers. Some stayed at the house for all ten years and some just a year or two.
All were great guys. Most thought of themselves as straight, but some didn't mind getting some blowjobs because they were extremely horny. A few were bisexuals and the sex with them was always great and long-lasting. There was always a lot of sex going on in the house, whether it was straight-stuff, watching porn together and jacking off, to out-right gay sex. Life has been great no matter how I look at it.
